We do this because we need a quick way to choose our compiler (cmake
chooses GNU on this system by default, and we have to use an MPI wrapper
compiler) and because we want those particular Fortran flags when the
MPI wrapper compiler is being used.
When I use this toolchain file, the Fortran compiler ID is unknown (I
failed to see this before, the C and CXX compiler IDs were correct).
However if I comment out the set CMAKE_Fortran_FLAGS line or if I skip
the toolchain file altogether and just pass
-DCMAKE_Fortran_COMPILER=mpxlf90 into the cmake command, the compiler ID
is VisualAge and everything works fine.
Am I misusing the toolchain file capability?
Yes, that should only be used for cross-compiling.
To set the compilers you can set the environment variables FC, CC, and
CXX before running CMake.
