How can I integrate Doxygen with CMake?

To integrate Doxygen with CMake, you can use the find_package command to locate Doxygen and then add a custom target to generate documentation.

Can you show me a sample CMakeLists.txt for this?

Sure! Here's a simple example:

find_package(Doxygen)

if(DOXYGEN_FOUND)
    set(DOXYGEN_OUTPUT_DIRECTORY ${CMAKE_CURRENT_BINARY_DIR}/docs)
    add_custom_target(doc ALL ${DOXYGEN_EXECUTABLE} ${CMAKE_CURRENT_SOURCE_DIR}/Doxyfile)
endif()

What should I include in the Doxyfile?

In the Doxyfile, you should set the INPUT to your source files and the OUTPUT_DIRECTORY to where you want the documentation to be generated.

Is there a way to automate the documentation generation during the build?

Yes, by adding the doc target to your build process, Doxygen will automatically generate documentation every time you build your project.
