🎯 CMake Documentation Target

Configuration Variables

The system automatically configures these CMake variables in Doxyfile.in:

@PROJECT_NAME@           # Project name from CMakeLists.txt
@PROJECT_VERSION@        # Version from CMakeLists.txt  
@PROJECT_DESCRIPTION@    # Project description
@CMAKE_SOURCE_DIR@       # Source directory path
@DOXYGEN_OUTPUT_DIR@     # Output directory (build/docs)
@DOXYGEN_DOT_FOUND@      # Whether Graphviz is available
@DOXYGEN_DOT_PATH@       # Path to Graphviz dot executable

CMake Options

BUILD_DOCUMENTATION=ON   # Enable documentation installation

CMake Targets

cmake --build build --target doxygen    # Build documentation
cmake --build build --target docs       # Alias for doxygen

🛠️ Usage Examples

Basic Documentation Build

# Configure with documentation support
mkdir build && cd build
cmake .. -DCMAKE_PREFIX_PATH=/opt/libtorch

# Build documentation
cmake --build . --target doxygen

# Documentation will be in build/docs/html/

Using the Build Script

# Simple build
./build_docs.sh

# Build and open in browser
./build_docs.sh --open

# Clean and rebuild
./build_docs.sh --clean --open

# Verbose output
./build_docs.sh --verbose

Installation with Documentation

# Configure with documentation installation
cmake .. -DBUILD_DOCUMENTATION=ON

# Install (includes documentation)
cmake --install . --component documentation

🔧 Advanced Configuration

Custom Doxyfile Settings

The Doxyfile.in template can be customized by modifying:

# Enable/disable specific outputs
GENERATE_LATEX         = NO    # LaTeX output
GENERATE_XML           = NO    # XML output
GENERATE_RTF           = NO    # RTF output

# Customize appearance
HTML_COLORSTYLE_HUE    = 220   # Blue theme
GENERATE_TREEVIEW      = YES   # Navigation tree
SEARCHENGINE           = YES   # Search functionality

Additional CMake Variables

Add custom variables in CMakeLists.txt:

set(PROJECT_AUTHOR "Your Name")
set(PROJECT_HOMEPAGE_URL "https://your-site.com")
# These will be available as @PROJECT_AUTHOR@ in Doxyfile.in

Output Customization

Modify output paths:

set(DOXYGEN_OUTPUT_DIR "${CMAKE_BINARY_DIR}/documentation")

🚀 CI/CD Integration

GitHub Actions

The workflow automatically:

1. Installs Doxygen and Graphviz
2. Configures CMake with documentation enabled
3. Builds documentation using the CMake target
4. Validates generated files
5. Deploys to GitHub Pages (on main branch)

Local Validation

The validation script checks:

• Doxygen availability
• Successful documentation generation
• Warning detection and reporting
• Essential file existence
• Documentation size verification

📈 Benefits
