Use FindDoxygen.cmake and deprecate our home-made doxygen.cmake? #742
Description
CMake 3.9 added an official module for finding, manipulating, and using Doxygen.
My proposal is that we could recommend to users that they use it and namely their doxygen_add_docs() function, to generate our documentation. It covers one major use case of doxygen.cmake which is the generation of a Doxyfile from CMake variables.
