I think the CMAKE_Fortran_COMPILER_ID variable should do the job...

if(CMAKE_Fortran_COMPILER_ID STREQUAL GNU)
  message(STATUS "Using GNU Fortran compiler")
elseif(CMAKE_Fortran_COMPILER_ID STREQUAL Intel)
  message(STATUS "Using Intel Fortran compiler")
else()
  message(STATUS "Using unknown Fortran compiler")
endif()
