It appears that add_definitions() places -DWHATEVER in the compile

compiler uses -D as a compile flag for something other than adding a
preprocessor definition. In order to pass a preprocessor definition,
you have to use -WF,-DWHATEVER.
What version of CMake are you using? This should work in 2.6.4 (and
perhaps earlier 2.6.x but I don't remember). There is a platform
configuration variable called "CMAKE_Fortran_DEFINE_FLAG" which is
set to "-WF,-D" for that compiler.
Add this to your project to see how the platform is set:
message("CMAKE_Fortran_DEFINE_FLAG=${CMAKE_Fortran_DEFINE_FLAG}")
message("CMAKE_Fortran_COMPILER_ID=${CMAKE_Fortran_COMPILER_ID}")
