-# AGENTS.md - Agent Guidelines for Assimp
-
-This document provides guidelines for AI agents working on the Assimp codebase.
-
-## Project Overview
-
-Assimp (Open Asset Import Library) is a C++ library that loads various 3D file formats into a shared, in-memory format. It supports 40+ import formats and several export formats.
-
-## Build Commands
-
-### Basic Build (CMake + Ninja recommended)
-```bash
-# Configure with CMake
-cmake -G Ninja -DASSIMP_BUILD_TESTS=ON -DASSIMP_WARNINGS_AS_ERRORS=ON -S . -B build
-
-# Build
-cmake --build build
-```
-
-### Key CMake Options
- `-DASSIMP_BUILD_TESTS=ON` - Build unit tests (default ON)
- `-DASSIMP_WARNINGS_AS_ERRORS=ON` - Treat warnings as errors (default ON)
- `-DASSIMP_BUILD_ASSIMP_TOOLS=ON` - Build command-line tools
- `-DASSIMP_BUILD_SAMPLES=ON` - Build sample applications
- `-DASSIMP_DOUBLE_PRECISION=ON` - Use double precision for calculations
- `-DASSIMP_NO_EXPORT=ON` - Disable export functionality
- `-DBUILD_SHARED_LIBS=OFF` - Build static library
-
-### Running Tests
-
-#### Run All Tests
-```bash
-# Using ctest
-cd build && ctest
-
-# Or run unit directly
-./build/unit
-```
-
-#### Run Single Test
-```bash
-# Using ctest with filter
-cd build && ctest -R "TestName"
-
-# Or run unit with filter
-./build/unit --gtest_filter="TestSuiteName.TestName"
-```
-
-For example:
-```bash
-./build/unit --gtest_filter="utObjImportExport.*"
-./build/unit --gtest_filter="utMaterialSystem.*"
-```
-
-#### Test Directory
-Tests are located in `test/unit/` and use Google Test. Test files are named `ut<Feature>.cpp`.
-
-## Code Style
-
-### Formatting
- **Use clang-format** before committing. Run: `clang-format -i <file>`
- The project uses a `.clang-format` file at the root with LLVM-based style
- Key settings:
-  - Indent width: 4 spaces
-  - Tab width: 4, UseTab: Never
-  - ColumnLimit: 0 (no line length limit)
-  - BreakConstructorInitializers: AfterColon
-  - AccessModifierOffset: -4
-
-### Header File Organization
-```cpp
-// Order of includes (use clang-format to enforce):
-// 1. Module's own header
-// 2. Other assimp headers (assimp/*)
-// 3. External headers (contrib/*)
-// 4. Standard library headers
-// 5. System headers
-
-#include "Common/Importer.h"
-#include <assimp/version.h>
-#include <assimp/config.h>
-#include "../contrib/some_lib/some.h"
-#include <vector>
-#include <string>
-```
-
-### Naming Conventions
- **Classes/Types**: PascalCase (e.g., `Importer`, `aiScene`)
- **Functions**: PascalCase (e.g., `ReadFile`, `GetExtension`)
- **Variables**: camelCase (e.g., `scene`, `importStep`)
- **Constants**: kCamelCase or UPPER_SNAKE_CASE (e.g., `kMaxVertices`)
- **Member variables**: Often prefixed with `m_` (e.g., `mScene`)
- **Static variables**: Often prefixed with `s_`
-
-### File Naming
- **Header files**: PascalCase (e.g., `Importer.h`, `ScenePrivate.h`)
- **Source files**: PascalCase (e.g., `Importer.cpp`)
- **Test files**: Prefixed with `ut` (e.g., `utObjImportExport.cpp`)
-
-### C++ Guidelines
-
-#### Language Standard
- Minimum: C++17
- Use modern C++ features (smart pointers, constexpr, etc.)
-
-#### Error Handling
- Use exceptions for recoverable errors (derived from `std::exception`)
- Use `ai_assert` for debugging assertions in code
- Return error codes from C API functions
-
-#### Classes
- Use `ai_enable_erasing` pattern for optional features
- Use PImpl idiom for ABI stability where appropriate
-
-#### Memory Management
- Use smart pointers (`std::unique_ptr`, `std::shared_ptr`)
- Prefer RAII patterns
- Document ownership semantics in function comments
-
-### Importers/Exporters
-
-#### Structure
-Each importer typically has:
-1. Header in `code/AssetLib/<Format>/`
-2. Implementation in `code/AssetLib/<Format>/`
-3. Registration in `code/Common/ImporterRegistry.cpp`
-4. Unit tests in `test/unit/ImportExport/`
-
-#### Registration
-```cpp
-void GetImporterInstanceList(std::vector<BaseImporter*>& out);
-// Add to registry
-out.push_back(new MyFormatImporter());
-```
-
-### Post-Processing
-
- Located in `code/PostProcessing/`
- Each process inherits from `BaseProcess`
- Implement `ExecuteOnScene` method
-
-### Documentation
-
- Use Doxygen-style comments for public APIs
- Example:
-```cpp
-/// <summary>
-/// Loads a file from disk.
-/// </summary>
-/// <param name="pFile">Path to the file.</param>
-/// <returns>Pointer to the imported scene.</returns>
-aiScene* Importer::ReadFile(const char* pFile);
-```
-
-### Contributing
-
-1. Create a fork of assimp
-2. Create a branch for your feature/fix
-3. Run `clang-format` on modified files
-4. Ensure tests pass
-5. Open a PR against `master` branch

-# Asset-Importer-Lib AI Tool Use Policy
-
-## Policy
-
-Assimp's policy is that contributors can use whatever tools they would like to
-craft their contributions, but there must be a **human in the loop**.
-**Contributors must read and review all LLM-generated code or text before they
-ask other project members to review it.** The contributor is always the author
-and is fully accountable for their contributions. Contributors should be
-sufficiently confident that the contribution is high enough quality that asking
-for a review is a good use of scarce maintainer time, and they should be **able
-to answer questions about their work** during review.
-
-We expect that new contributors will be less confident in their contributions,
-and our guidance to them is to **start with small contributions** that they can
-fully understand to build confidence. We aspire to be a welcoming community
-that helps new contributors grow their expertise, but learning involves taking
-small steps, getting feedback, and iterating. Passing maintainer feedback to an
-LLM doesn't help anyone grow, and does not sustain our community.
-
-Contributors are expected to **be transparent and label contributions that
-contain substantial amounts of tool-generated content**. Our policy on
-labelling is intended to facilitate reviews, and not to track which parts of
-Assimp are generated. Contributors should note tool usage in their pull request
-description, commit message, or wherever authorship is normally indicated for
-the work. For instance, use a commit message trailer like Assisted-by: <name of
-code assistant>. This transparency helps the community develop best practices
-and understand the role of these new tools.
-
-This policy includes, but is not limited to, the following kinds of
-contributions:
-
- Code, usually in the form of a pull request
- RFCs or design proposals
- Issues or security vulnerabilities
- Comments and feedback on pull requests
-
-## Details
-
-To ensure sufficient self review and understanding of the work, it is strongly
-recommended that contributors write PR descriptions themselves (if needed,
-using tools for translation or copy-editing). The description should explain
-the motivation, implementation approach, expected impact, and any open
-questions or uncertainties to the same extent as a contribution made without
-tool assistance.
-
-AI tools must not be used to fix GitHub issues labelled [`good first
-issue`][good-first-issue]. These issues are generally not urgent, and are
-intended to be learning opportunities for new contributors to get familiar with
-the codebase. Whether you are a newcomer or not, fully automating the process
-of fixing this issue squanders the learning opportunity and doesn't add much
-value to the project. **Using AI tools to fix issues labelled as "good first
-issues" is forbidden**.
-
-[good-first-issue]: https://github.com/llvm/llvm-project/issues/?q=is%3Aissue%20state%3Aopen%20label%3A%22good%20first%20issue%22
-
-## Extractive Contributions
-
-The reason for our "human-in-the-loop" contribution policy is that processing
-patches, PRs, RFCs, and comments to Assimp is not free -- it takes a lot of
-maintainer time and energy to review those contributions! Sending the
-unreviewed output of an Assimp to open source project maintainers *extracts* work
-from them in the form of design and code review, so we call this kind of
-contribution an "extractive contribution".
-
-Our **golden rule** is that a contribution should be worth more to the project
-than the time it takes to review it. These ideas are captured by this quote
-from the book [Working in Public][public] by Nadia Eghbal:
-
-[public]: https://press.stripe.com/working-in-public
-
-> \"When attention is being appropriated, producers need to weigh the costs and
-> benefits of the transaction. To assess whether the appropriation of attention
-> is net-positive, it's useful to distinguish between *extractive* and
-> *non-extractive* contributions. Extractive contributions are those where the
-> marginal cost of reviewing and merging that contribution is greater than the
-> marginal benefit to the project's producers. In the case of a code
-> contribution, it might be a pull request that's too complex or unwieldy to
-> review, given the potential upside.\" \-- Nadia Eghbal
-
-Prior to the advent of LLMs, open source project maintainers would often review
-any and all changes sent to the project simply because posting a change for
-review was a sign of interest from a potential long-term contributor. While new
-tools enable more development, it shifts effort from the implementor to the
-reviewer, and our policy exists to ensure that we value and do not squander
-maintainer time.
-
-Reviewing changes from new contributors is part of growing the next generation
-of contributors and sustaining the project. We want the LLVM project to be
-welcoming and open to aspiring compiler engineers who are willing to invest
-time and effort to learn and grow, because growing our contributor base and
-recruiting new maintainers helps sustain the project over the long term. Being
-open to contributions and [liberally granting commit access][commit-access]
-is a big part of how LLVM has grown and successfully been adopted all across
-the industry.  We therefore automatically post a greeting comment to pull
-requests from new contributors and encourage maintainers to spend their time to
-help new contributors learn.
-
-[commit-access]: https://llvm.org/docs/DeveloperPolicy.html#obtaining-commit-access
-
-## Handling Violations
-
-If a maintainer judges that a contribution doesn't comply with this policy,
-they should paste the following response to request changes:
-
-    This PR doesn't appear to comply with our policy on tool-generated content,
-    and requires additional justification for why it is valuable enough to the
-    project for us to review it. Please see our developer policy on
-    AI-generated contributions: http://llvm.org/docs/AIToolPolicy.html
-
-The best ways to make a change less extractive and more valuable are to reduce
-its size or complexity or to increase its usefulness to the community. These
-factors are impossible to weigh objectively, and our project policy leaves this
-determination up to the maintainers of the project, i.e. those who are doing
-the work of sustaining the project.
-
-If or when it becomes clear that a GitHub issue or PR is off-track and not
-moving in the right direction, maintainers should apply the `extractive` label
-to help other reviewers prioritize their review time.
-
-If a contributor fails to make their change meaningfully less extractive,
-maintainers should escalate to the relevant moderation or admin team for the
-space (GitHub, Discourse, Discord, etc) to lock the conversation.
-
-## Copyright
-
-Artificial intelligence systems raise many questions around copyright that have
-yet to be answered. Our policy on AI tools is similar to our copyright policy:
-Contributors are responsible for ensuring that they have the right to
-contribute code under the terms of our license, typically meaning that either
-they, their employer, or their collaborators hold the copyright. Using AI tools
-to regenerate copyrighted material does not remove the copyright, and
-contributors are responsible for ensuring that such material does not appear in
-their contributions. Contributions found to violate this policy will be removed
-just like any other offending contribution.
-
-## Examples
-
-Here are some examples of contributions that demonstrate how to apply
-the principles of this policy:
-
- [This PR][alive-pr] contains a proof from Alive2, which is a strong signal of
-  value and correctness.
- This [generated documentation][gsym-docs] was reviewed for correctness by a
-  human before being posted.
-

+#
+# ::
+#
+#    IL_LIBRARIES -   the name of the IL library. These include the full path to
+#                     the core DevIL library. This one has to be linked into the
+#                     application.
+#    ILU_LIBRARIES -  the name of the ILU library. Again, the full path. This
+#                     library is for filters and effects, not actual loading. It
+#                     doesn't have to be linked if the functionality it provides
+#                     is not used.
+#    ILUT_LIBRARIES - the name of the ILUT library. Full path. This part of the
+#                     library interfaces with OpenGL. It is not strictly needed
+#                     in applications.
+#    IL_INCLUDE_DIR - where to find the il.h, ilu.h and ilut.h files.
+#    IL_FOUND -       this is set to TRUE if all the above variables were set.
+#                     This will be set to false if ILU or ILUT are not found,
+#                     even if they are not needed. In most systems, if one
+#                     library is found all the others are as well. That's the
+#                     way the DevIL developers release it.
