I'm using doxygen for my C++ project documentation. The project's version related API is version.hpp, generated from version.hpp.in via cmake's configure_file commands. Thus, version.hpp is located in @CMAKE_BINARY_DIR instead of CMAKE_SOURCE_DIR.
Here comes the question: I documented version.hpp.in, generated doxygen page from version.hpp, but I would like to mark the APIs' including path as ${CMAKE_SOURCE_DIR} (a relative path), instead of ${CMAKE_BINARY_DIR} ( a full path). How can I do that?
