+description: Find duplicate GitHub issues
+---
+
+Find up to 3 likely duplicate issues for a given GitHub issue.
+
+To do this, follow these steps precisely:
+
+1. Use an agent to check if the Github issue (a) is closed, (b) does not need to be deduped (eg. because it is broad product feedback without a specific solution, or positive feedback), or (c) already has a duplicates comment that you made earlier. If so, do not proceed.
+2. Use an agent to view a Github issue, and ask the agent to return a summary of the issue
+3. Then, launch 5 parallel agents to search Github for duplicates of this issue, using diverse keywords and search approaches, using the summary from #1
+4. Next, feed the results from #1 and #2 into another agent, so that it can filter out false positives, that are likely not actually duplicates of the original issue. If there are no duplicates remaining, do not proceed.
+5. Finally, comment back on the issue with a list of up to three duplicate issues (or zero, if there are no likely duplicates)
+
+Notes (be sure to tell this to your agents, too):
+
+- Use `gh` to interact with Github, rather than web fetch
+- Do not use other tools, beyond `gh` (eg. don't use other MCP servers, file edit, etc.)
+- Make a todo list first
+- For your comment, follow the following format precisely (assuming for this example that you found 3 suspected duplicates):
+
+---
+
+Found 3 possible duplicate issues:
+
+1. <link to issue>
+2. <link to issue>
+3. <link to issue>
+
+This issue will be automatically closed as a duplicate in 3 days.
+
+- If your issue is a duplicate, please close it and 👍 the existing issue instead
+- To prevent auto-closure, add a comment or 👎 this comment

+description: Triage GitHub issues and label critical ones for oncall
+---
+
+You're an oncall triage assistant for GitHub issues. Your task is to identify critical issues that require immediate oncall attention and apply the "oncall" label.
+
+Repository: OrcaSlicer/OrcaSlicer
+
+Task overview:
+
+1. First, get all open bugs updated in the last 3 days with at least 50 engagements:
+   ```bash
+   gh issue list --repo OrcaSlicer/OrcaSlicer --state open --label bug --limit 1000 --json number,title,updatedAt,comments,reactions | jq -r '.[] | select((.updatedAt >= (now - 259200 | strftime("%Y-%m-%dT%H:%M:%SZ"))) and ((.comments | length) + ([.reactions[].content] | length) >= 50)) | "\(.number)"'
+   ```
+
+2. Save the list of issue numbers and create a TODO list with ALL of them. This ensures you process every single one.
+
+3. For each issue in your TODO list:
+   - Use `gh issue view <number> --repo OrcaSlicer/OrcaSlicer --json title,body,labels,comments` to get full details
+   - Read and understand the full issue content and comments to determine actual user impact
+   - Evaluate: Is this truly blocking users from using Claude Code?
+     - Consider: "crash", "stuck", "frozen", "hang", "unresponsive", "cannot use", "blocked", "broken"
+     - Does it prevent core functionality? Can users work around it?
+   - Be conservative - only flag issues that truly prevent users from getting work done
+
+4. For issues that are truly blocking and don't already have the "oncall" label:
+   - Use `gh issue edit <number> --repo OrcaSlicer/OrcaSlicer --add-label "oncall"`
+   - Mark the issue as complete in your TODO list
+
+5. After processing all issues, provide a summary:
+   - List each issue number that received the "oncall" label
+   - Include the issue title and brief reason why it qualified
+   - If no issues qualified, state that clearly
+
+Important:
+- Process ALL issues in your TODO list systematically
+- Don't post any comments to issues
+- Only add the "oncall" label, never remove it
+- Use individual `gh issue view` commands instead of bash for loops to avoid approval prompts

+# Repository Guidelines
+
+## Project Structure & Module Organization
+OrcaSlicer’s C++17 sources live in `src/`, split by feature modules and platform adapters. User assets, icons, and printer presets are in `resources/`; translations stay in `localization/`. Tests sit in `tests/`, grouped by domain (`libslic3r/`, `sla_print/`, etc.) with fixtures under `tests/data/`. CMake helpers reside in `cmake/`, and longer references in `doc/` and `SoftFever_doc/`. Automation scripts belong in `scripts/` and `tools/`. Treat everything in `deps/` and `deps_src/` as vendored snapshots—do not modify without mirroring upstream tags.
+
+## Build, Test, and Development Commands
+Use out-of-source builds:
+- `cmake -S . -B build -DCMAKE_BUILD_TYPE=Release` configures dependencies and generates build files.
+- `cmake --build build --target OrcaSlicer --config Release` compiles the app; add `--parallel` to speed up.
+- `cmake --build build --target tests` then `ctest --test-dir build --output-on-failure` runs automated suites.
+Platform helpers such as `build_linux.sh`, `build_release_macos.sh`, and `build_release_vs2022.bat` wrap the same flow with toolchain flags. Use `build_release_macos.sh -sx` when reproducing macOS build issues, and `scripts/DockerBuild.sh` for reproducible container builds.
+
+## Coding Style & Naming Conventions
+`.clang-format` enforces 4-space indents, a 140-column limit, aligned initializers, and brace wrapping for classes and functions. Run `clang-format -i <file>` before committing; the CMake `clang-format` target is available when LLVM tools are on your PATH. Prefer `CamelCase` for classes, `snake_case` for functions and locals, and `SCREAMING_CASE` for constants, matching conventions in `src/`. Keep headers self-contained and align include order with the IWYU pragmas.
+
+## Testing Guidelines
+Unit tests rely on Catch2 (`tests/catch2/`). Name specs after the component under test—for example `tests/libslic3r/TestPlanarHole.cpp`—and tag long-running cases so `ctest -L fast` remains useful. Cover new algorithms with deterministic fixtures or sample G-code stored in `tests/data/`. Document manual printer validation or regression slicer checks in your PR when automated coverage is insufficient.
+
+## Commit & Pull Request Guidelines
+The history favors concise, sentence-style subject lines with optional issue references, e.g., `Fix grid lines origin for multiple plates (#10724)`. Squash fixups locally before opening a PR. Complete `.github/pull_request_template.md`, include reproduction steps or screenshots for UI changes, and mention impacted presets or translations. Link issues via `Closes #NNNN` when applicable, and call out dependency bumps or profile migrations for maintainer review.
+
+## Security & Configuration Tips
+Follow `SECURITY.md` for vulnerability reporting. Keep API tokens and printer credentials out of tracked configs; use `sandboxes/` for experimental settings. When touching third-party code in `deps_src/`, record the upstream commit or release in your PR description and run the relevant platform build script to confirm integration.

+## Overview
+
+OrcaSlicer is an open-source 3D slicer application forked from Bambu Studio, built using C++ with wxWidgets for the GUI and CMake as the build system. The project uses a modular architecture with separate libraries for core slicing functionality, GUI components, and platform-specific code.

+
+
+### Build System
+- Uses CMake with minimum version 3.13 (maximum 3.31.x on Windows)
+- Primary build directory: `build/`
+- Dependencies are built in `deps/build/`
+- The build process is split into dependency building and main application building
+- Windows builds use Visual Studio generators
+- macOS builds use Xcode by default, Ninja with -x flag
+- Linux builds use Ninja generator
+
+### Testing
+Tests are located in the `tests/` directory and use the Catch2 testing framework. Test structure:
+- `tests/libslic3r/` - Core library tests (21 test files)
+  - Geometry processing, algorithms, file formats (STL, 3MF, AMF)
+  - Polygon operations, clipper utilities, Voronoi diagrams
+- `tests/fff_print/` - Fused Filament Fabrication tests (12 test files)
+  - Slicing algorithms, G-code generation, print mechanics
+  - Fill patterns, extrusion, support material
+- `tests/sla_print/` - Stereolithography tests (4 test files)
+  - SLA-specific printing algorithms, support generation
+- `tests/libnest2d/` - 2D nesting algorithm tests
+- `tests/slic3rutils/` - Utility function tests
+- `tests/sandboxes/` - Experimental/sandbox test code
+
+Run all tests after building:
+```bash
+cd build && ctest
+```
+
+Run tests with verbose output:
+```bash
+cd build && ctest --output-on-failure
+```
+
+Run individual test suites:
+```bash
+# From build directory
+ctest --test-dir ./tests/libslic3r/libslic3r_tests
+ctest --test-dir ./tests/fff_print/fff_print_tests
+ctest --test-dir ./tests/sla_print/sla_print_tests
+# and so on
+```
+

+- **Memory management**: Prefer smart pointers, RAII patterns
+- **Thread safety**: Use TBB for parallelization, be mindful of shared state
+
+### Common Development Tasks
+
+#### Adding New Print Settings
+1. Define setting in `PrintConfig.cpp` with proper bounds and defaults
+2. Add UI controls in appropriate GUI components  
+3. Update serialization in config save/load
+4. Add tooltips and help text for user guidance
+5. Test with different printer profiles
+
+#### Modifying Slicing Algorithms  
+1. Core algorithms live in `libslic3r/` subdirectories
+2. Performance-critical code should be profiled and optimized
+3. Consider multi-threading implications (TBB integration)
+4. Validate changes don't break existing profiles
+5. Add regression tests where appropriate
+
+#### GUI Development
+1. GUI code resides in `src/slic3r/GUI/` (not visible in current tree)
+2. Use existing wxWidgets patterns and custom controls
+3. Support both light and dark themes
+4. Consider DPI scaling on high-resolution displays
+5. Maintain cross-platform compatibility
+
+#### Adding Printer Support
+1. Create JSON profile in `resources/profiles/[manufacturer].json`
+2. Add printer-specific start/end G-code templates
+3. Configure build volume, capabilities, and material compatibility
+4. Test thoroughly with actual hardware when possible
+5. Follow existing profile structure and naming conventions
+
+### Dependencies and Build System
+- **CMake-based** with separate dependency building phase
+- **Dependencies** built once in `deps/build/`, then linked to main application  
+- **Cross-platform** considerations important for all changes
+- **Resource files** embedded at build time, platform-specific handling
+
+### Performance Considerations
+- **Slicing algorithms** are CPU-intensive, profile before optimizing
+- **Memory usage** can be substantial with complex models
+- **Multi-threading** extensively used via TBB
+- **File I/O** optimized for large 3MF files with embedded textures
+- **Real-time preview** requires efficient mesh processing
+
+## Important Development Notes
+
+### Codebase Navigation
+- Use search tools extensively - codebase has 500k+ lines
+- Key entry points: `src/OrcaSlicer.cpp` for application startup
+- Core slicing: `libslic3r/Print.cpp` orchestrates the slicing pipeline
+- Configuration: `PrintConfig.cpp` defines all print/printer/material settings
+
+### Compatibility and Stability
+- **Backward compatibility** maintained for project files and profiles
+- **Cross-platform** support essential (Windows/macOS/Linux)  
+- **File format** changes require careful version handling
+- **Profile migrations** needed when settings change significantly
+
+### Quality and Testing
+- **Regression testing** important due to algorithm complexity
+- **Performance benchmarks** help catch performance regressions
+- **Memory leak** detection important for long-running GUI application
+- **Cross-platform** testing required before releases

+                       Version 3, 19 November 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The GNU Affero General Public License is a free, copyleft license for
+software and other kinds of works, specifically designed to ensure
+cooperation with the community in the case of network server software.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+our General Public Licenses are intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  Developers that use our General Public Licenses protect your rights
+with two steps: (1) assert copyright on the software, and (2) offer
+you this License which gives you legal permission to copy, distribute
+and/or modify the software.
+
+  A secondary benefit of defending all users' freedom is that
+improvements made in alternate versions of the program, if they
+receive widespread use, become available for other developers to
+incorporate.  Many developers of free software are heartened and
+encouraged by the resulting cooperation.  However, in the case of
+software used on network servers, this result may fail to come about.
+The GNU General Public License permits making a modified version and
+letting the public access it on a server without ever releasing its
+source code to the public.
+
+  The GNU Affero General Public License is designed specifically to
+ensure that, in such cases, the modified source code becomes available
+to the community.  It requires the operator of a network server to
+provide the source code of the modified version running there to the
+users of that server.  Therefore, public use of a modified version, on
+a publicly accessible server, gives the public access to the source
+code of the modified version.
+
+  An older license, called the Affero General Public License and
+published by Affero, was designed to accomplish similar goals.  This is
+a different license, not a version of the Affero GPL, but Affero has
+released a new version of the Affero GPL which permits relicensing under
+this license.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU Affero General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Remote Network Interaction; Use with the GNU General Public License.
+
+  Notwithstanding any other provision of this License, if you modify the
+Program, your modified version must prominently offer all users
+interacting with it remotely through a computer network (if your version
+supports such interaction) an opportunity to receive the Corresponding
+Source of your version by providing access to the Corresponding Source
+from a network server at no charge, through some standard or customary
+means of facilitating copying of software.  This Corresponding Source
+shall include the Corresponding Source for any work covered by version 3
+of the GNU General Public License that is incorporated pursuant to the
+following paragraph.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the work with which it is combined will remain governed by version
+3 of the GNU General Public License.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU Affero General Public License from time to time.  Such new versions
+will be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU Affero General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU Affero General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU Affero General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software: you can redistribute it and/or modify
+    it under the terms of the GNU Affero General Public License as published by
+    the Free Software Foundation, either version 3 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU Affero General Public License for more details.
+
+    You should have received a copy of the GNU Affero General Public License
+    along with this program.  If not, see <http://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+  If your software can interact with users remotely through a computer
+network, you should also make sure that it provides a way for users to
+get its source.  For example, if your program is a web application, its
+interface could display a "Source" link that leads users to an archive
+of the code.  There are many ways you could offer source, and different
+solutions will be better for different programs; see section 13 for the
+specific requirements.
+
+  You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU AGPL, see
+<http://www.gnu.org/licenses/>.

+Find the OpenGL Extension Wrangler Library (GLEW)
+
+Input Variables
+^^^^^^^^^^^^^^^
+
+The following variables may be set to influence this module’s behavior:
+
+``GLEW_USE_STATIC_LIBS``
+  to find and create :prop_tgt:`IMPORTED` target for static linkage.
+
+``GLEW_VERBOSE``
+  to output a detailed log of this module.
+
+Imported Targets
+^^^^^^^^^^^^^^^^
+
+This module defines the following :ref:`Imported Targets <Imported Targets>`:
+
+
+``GLEW::glew``
+  The GLEW shared library.
+``GLEW::glew_s``
+  The GLEW static library, if ``GLEW_USE_STATIC_LIBS`` is set to ``TRUE``.
+``GLEW::GLEW``
+  Duplicates either ``GLEW::glew`` or ``GLEW::glew_s`` based on availability.
+
+Result Variables
+^^^^^^^^^^^^^^^^
+
+This module defines the following variables:
+
+``GLEW_INCLUDE_DIRS``
+  include directories for GLEW
+``GLEW_LIBRARIES``
+  libraries to link against GLEW
+``GLEW_SHARED_LIBRARIES``
+  libraries to link against shared GLEW
+``GLEW_STATIC_LIBRARIES``
+  libraries to link against static GLEW
+``GLEW_FOUND``
+  true if GLEW has been found and can be used
+``GLEW_VERSION``
+  GLEW version
+``GLEW_VERSION_MAJOR``
+  GLEW major version
+``GLEW_VERSION_MINOR``
+  GLEW minor version
+``GLEW_VERSION_MICRO``
+  GLEW micro version

+FindOpenVDB
+-----------
+
+Find OpenVDB include dirs, libraries and settings
+
+Use this module by invoking find_package with the form::
+
+  find_package(OpenVDB
+    [version] [EXACT]      # Minimum or EXACT version
+    [REQUIRED]             # Fail with error if OpenVDB is not found
+    [COMPONENTS <libs>...] # OpenVDB libraries by their canonical name
+                           # e.g. "openvdb" for "libopenvdb"
+    )
+
+IMPORTED Targets
+^^^^^^^^^^^^^^^^
+
+``OpenVDB::openvdb``
+  The core openvdb library target.
+
+Result Variables
+^^^^^^^^^^^^^^^^
+
+This will define the following variables:
+
+``OpenVDB_FOUND``
+  True if the system has the OpenVDB library.
+``OpenVDB_VERSION``
+  The version of the OpenVDB library which was found.
+``OpenVDB_INCLUDE_DIRS``
+  Include directories needed to use OpenVDB.
+``OpenVDB_LIBRARIES``
+  Libraries needed to link to OpenVDB.
+``OpenVDB_LIBRARY_DIRS``
+  OpenVDB library directories.
+``OpenVDB_DEFINITIONS``
+  Definitions to use when compiling code that uses OpenVDB.
+``OpenVDB_{COMPONENT}_FOUND``
+  True if the system has the named OpenVDB component.
+``OpenVDB_USES_BLOSC``
+  True if the OpenVDB Library has been built with blosc support
+``OpenVDB_USES_LOG4CPLUS``
+  True if the OpenVDB Library has been built with log4cplus support
+``OpenVDB_USES_EXR``
+  True if the OpenVDB Library has been built with openexr support
+``OpenVDB_ABI``
+  Set if this module was able to determine the ABI number the located
+  OpenVDB Library was built against. Unset otherwise.
+
+Cache Variables
+^^^^^^^^^^^^^^^
+
+The following cache variables may also be set:
+
+``OpenVDB_INCLUDE_DIR``
+  The directory containing ``openvdb/version.h``.
+``OpenVDB_{COMPONENT}_LIBRARY``
+  Individual component libraries for OpenVDB
+
+Hints
+^^^^^
+
+Instead of explicitly setting the cache variables, the following variables
+may be provided to tell this module where to look.
+
+``OPENVDB_ROOT``
+  Preferred installation prefix.
+``OPENVDB_INCLUDEDIR``
+  Preferred include directory e.g. <prefix>/include
+``OPENVDB_LIBRARYDIR``
+  Preferred library directory e.g. <prefix>/lib
+``SYSTEM_LIBRARY_PATHS``
+  Paths appended to all include and lib searches.
+
+#]=======================================================================]
+

+FindPackageHandleStandardArgs
+-----------------------------
+
+This module provides a function intended to be used in :ref:`Find Modules`
+implementing :command:`find_package(<PackageName>)` calls.  It handles the
+``REQUIRED``, ``QUIET`` and version-related arguments of ``find_package``.
+It also sets the ``<PackageName>_FOUND`` variable.  The package is
+considered found if all variables listed contain valid results, e.g.
+valid filepaths.
+
+.. command:: find_package_handle_standard_args
+
+  There are two signatures::
+
+    find_package_handle_standard_args(<PackageName>
+      (DEFAULT_MSG|<custom-failure-message>)
+      <required-var>...
+      )
+
+    find_package_handle_standard_args(<PackageName>
+      [FOUND_VAR <result-var>]
+      [REQUIRED_VARS <required-var>...]
+      [VERSION_VAR <version-var>]
+      [HANDLE_COMPONENTS]
+      [CONFIG_MODE]
+      [FAIL_MESSAGE <custom-failure-message>]
+      )
+
+  The ``<PackageName>_FOUND`` variable will be set to ``TRUE`` if all
+  the variables ``<required-var>...`` are valid and any optional
+  constraints are satisfied, and ``FALSE`` otherwise.  A success or
+  failure message may be displayed based on the results and on
+  whether the ``REQUIRED`` and/or ``QUIET`` option was given to
+  the :command:`find_package` call.
+
+  The options are:
+
+  ``(DEFAULT_MSG|<custom-failure-message>)``
+    In the simple signature this specifies the failure message.
+    Use ``DEFAULT_MSG`` to ask for a default message to be computed
+    (recommended).  Not valid in the full signature.
+
+  ``FOUND_VAR <result-var>``
+    Obsolete.  Specifies either ``<PackageName>_FOUND`` or
+    ``<PACKAGENAME>_FOUND`` as the result variable.  This exists only
+    for compatibility with older versions of CMake and is now ignored.
+    Result variables of both names are always set for compatibility.
+
+  ``REQUIRED_VARS <required-var>...``
+    Specify the variables which are required for this package.
+    These may be named in the generated failure message asking the
+    user to set the missing variable values.  Therefore these should
+    typically be cache entries such as ``FOO_LIBRARY`` and not output
+    variables like ``FOO_LIBRARIES``.
+
+  ``VERSION_VAR <version-var>``
+    Specify the name of a variable that holds the version of the package
+    that has been found.  This version will be checked against the
+    (potentially) specified required version given to the
+    :command:`find_package` call, including its ``EXACT`` option.
+    The default messages include information about the required
+    version and the version which has been actually found, both
+    if the version is ok or not.
+
+  ``HANDLE_COMPONENTS``
+    Enable handling of package components.  In this case, the command
+    will report which components have been found and which are missing,
+    and the ``<PackageName>_FOUND`` variable will be set to ``FALSE``
+    if any of the required components (i.e. not the ones listed after
+    the ``OPTIONAL_COMPONENTS`` option of :command:`find_package`) are
+    missing.
+
+  ``CONFIG_MODE``
+    Specify that the calling find module is a wrapper around a
+    call to ``find_package(<PackageName> NO_MODULE)``.  This implies
+    a ``VERSION_VAR`` value of ``<PackageName>_VERSION``.  The command
+    will automatically check whether the package configuration file
+    was found.
+
+  ``FAIL_MESSAGE <custom-failure-message>``
+    Specify a custom failure message instead of using the default
+    generated message.  Not recommended.
+
+Example for the simple signature:
+
+.. code-block:: cmake
+
+  find_package_handle_standard_args(LibXml2 DEFAULT_MSG
+    LIBXML2_LIBRARY LIBXML2_INCLUDE_DIR)
+
+The ``LibXml2`` package is considered to be found if both
+``LIBXML2_LIBRARY`` and ``LIBXML2_INCLUDE_DIR`` are valid.
+Then also ``LibXml2_FOUND`` is set to ``TRUE``.  If it is not found
+and ``REQUIRED`` was used, it fails with a
+:command:`message(FATAL_ERROR)`, independent whether ``QUIET`` was
+used or not.  If it is found, success will be reported, including
+the content of the first ``<required-var>``.  On repeated CMake runs,
+the same message will not be printed again.
+
+Example for the full signature:
+
+.. code-block:: cmake
+
+  find_package_handle_standard_args(LibArchive
+    REQUIRED_VARS LibArchive_LIBRARY LibArchive_INCLUDE_DIR
+    VERSION_VAR LibArchive_VERSION)
+
+In this case, the ``LibArchive`` package is considered to be found if
+both ``LibArchive_LIBRARY`` and ``LibArchive_INCLUDE_DIR`` are valid.
+Also the version of ``LibArchive`` will be checked by using the version
+contained in ``LibArchive_VERSION``.  Since no ``FAIL_MESSAGE`` is given,
+the default messages will be printed.
+
+Another example for the full signature:
+
+.. code-block:: cmake
+
+  find_package(Automoc4 QUIET NO_MODULE HINTS /opt/automoc4)
+  find_package_handle_standard_args(Automoc4  CONFIG_MODE)
+
+In this case, a ``FindAutmoc4.cmake`` module wraps a call to
+``find_package(Automoc4 NO_MODULE)`` and adds an additional search
+directory for ``automoc4``.  Then the call to
+``find_package_handle_standard_args`` produces a proper success/failure
+message.

+#               [[COMPONENTS] [components...]]
+#               [OPTIONAL_COMPONENTS components...]) 
+#
+# where the allowed components are tbbmalloc and tbb_preview. Users may modify 
+# the behavior of this module with the following variables:
+#
+# * TBB_ROOT_DIR          - The base directory the of TBB installation.
+# * TBB_INCLUDE_DIR       - The directory that contains the TBB headers files.
+# * TBB_LIBRARY           - The directory that contains the TBB library files.
+# * TBB_<library>_LIBRARY - The path of the TBB the corresponding TBB library. 
+#                           These libraries, if specified, override the 
+#                           corresponding library search results, where <library>

+#                           tbb_preview, or tbb_preview_debug.
+# * TBB_USE_DEBUG_BUILD   - The debug version of tbb libraries, if present, will
+#                           be used instead of the release version.
+# * TBB_STATIC            - Static linking of libraries with a _static suffix.
+#                           For example, on Windows a tbb_static.lib will be searched for
+#                           instead of tbb.lib.
+#
+# Users may modify the behavior of this module with the following environment
+# variables:
+#
+# * TBB_INSTALL_DIR 
+# * TBBROOT
+# * LIBRARY_PATH
+#
+# This module will set the following variables:

+#                           don’t want to use TBB.
+# * TBB_<component>_FOUND - If False, optional <component> part of TBB system is
+#                           not available.
+# * TBB_VERSION           - The full version string
+# * TBB_VERSION_MAJOR     - The major version
+# * TBB_VERSION_MINOR     - The minor version
+# * TBB_INTERFACE_VERSION - The interface version number defined in 
+#                           tbb/tbb_stddef.h.
+# * TBB_<library>_LIBRARY_RELEASE - The path of the TBB release version of 
+#                           <library>, where <library> may be tbb, tbb_debug,
+#                           tbbmalloc, tbbmalloc_debug, tbb_preview, or 
+#                           tbb_preview_debug.
+# * TBB_<library>_LIBRARY_DEGUG - The path of the TBB release version of 
+#                           <library>, where <library> may be tbb, tbb_debug,
+#                           tbbmalloc, tbbmalloc_debug, tbb_preview, or

+------------------
+
+A utility CMake file which provides helper functions for configuring an
+OpenVDB installation.
+
+Use this module by invoking include with the form::
+
+  include ( OpenVDBUtils )
+
+
+The following functions are provided:
+
+``OPENVDB_VERSION_FROM_HEADER``
+
+  OPENVDB_VERSION_FROM_HEADER ( <header_path>
+    VERSION [<version>]
+    MAJOR   [<version>]
+    MINOR   [<version>]
+    PATCH   [<version>] )
+
+  Parse the provided version file to retrieve the current OpenVDB
+  version information. The file is expected to be a version.h file
+  as found in the following path of an OpenVDB repository:
+    openvdb/version.h
+
+  If the file does not exist, variables are unmodified.
+
+``OPENVDB_ABI_VERSION_FROM_PRINT``
+
+  OPENVDB_ABI_VERSION_FROM_PRINT ( <vdb_print>
+    [QUIET]
+    ABI [<version>] )
+
+  Retrieve the ABI version that an installation of OpenVDB was compiled
+  for using the provided vdb_print binary. Parses the result of:
+    vdb_print --version
+
+  If the binary does not exist or fails to launch, variables are
+  unmodified.

+#
+# Options:
+#
+#   FORCEINCLUDE: Add compiler flags to automatically include the
+#   pchheader.h from every source file. Works with both GCC and
+#   MSVC. This is recommended.
+#
+#   SOURCE_C/CXX: Specifies the .c/.cpp source file that includes
+#   pchheader.h for generating the pre-compiled header
+#   output. Defaults to pchheader.c. Only required for MSVC.
+#
+# Caveats:
+#
+#   * Its not currently possible to use the same precompiled-header in
+#     more than a single target in the same directory (No way to set
+#     the source file properties differently for each target).
+#
+#   * MSVC: A source file with the same name as the header must exist
+#     and be included in the target (E.g. header.cpp). Name of file
+#     can be changed using the SOURCE_CXX/SOURCE_C options.

+# select_library_configurations( basename )
+#
+# This macro takes a library base name as an argument, and will choose
+# good values for basename_LIBRARY, basename_LIBRARIES,
+# basename_LIBRARY_DEBUG, and basename_LIBRARY_RELEASE depending on what
+# has been found and set.  If only basename_LIBRARY_RELEASE is defined,
+# basename_LIBRARY will be set to the release value, and
+# basename_LIBRARY_DEBUG will be set to basename_LIBRARY_DEBUG-NOTFOUND.
+# If only basename_LIBRARY_DEBUG is defined, then basename_LIBRARY will
+# take the debug value, and basename_LIBRARY_RELEASE will be set to
+# basename_LIBRARY_RELEASE-NOTFOUND.
+#
+# If the generator supports configuration types, then basename_LIBRARY
+# and basename_LIBRARIES will be set with debug and optimized flags
+# specifying the library to be used for the given configuration.  If no
+# build type has been set or the generator in use does not support
+# configuration types, then basename_LIBRARY and basename_LIBRARIES will
+# take only the release value, or the debug value if the release one is
+# not set.
