Why

There are a few things this package can do that can not be done easily with the Doxygen module bundled with CMake:

• One can provide a prepared project file instead of using the default + CMake overrides formula. The input arguments will be merged into the final project file.

• The input project is parsed to set up the target dependencies on extra files, such as a custom stylesheet, HTML header/footer, etc. The documentation build will correctly re-trigger when those files are modified.

• Environment-specific properties, such as HAVE_DOT, WARN_FORMAT, etc., will be set automatically.

• PDF generation is supported (from the generated LaTex sources).
