[CMake] What do I need to do to insure that CMake uses gfortran?

[Conan]

Yes, I cleared the build directory before each run of cmake.  I 
eventually just added the following lines:

SET (CMAKE_Fortran_COMPILER  gfortran)
SET (CMAKE_CC_COMPILER  gcc)
SET (CMAKE_CXX_COMPILER  g++)

Not sure if that is the "approved" way to do this but that got me back 
on track.

C
