Tim, I guess the difference is "project" command defines CMAKE_CXX_FLAGS_DEBUG and does not define CMAKE_Fortran_FLAGS_DEBUG.
Regarding CMAKE_*_FLAGS_*_INIT, you are right, but what if user explicitly set the same value as INIT? It would be overwritten! Anyway, I am happy with the solution to put CMAKE_CXX_FLAGS_DEBUG before "project" command.
