[CMake] MPI Compilers

[Tim Gallagher]

Along similar lines, we have it currently working with:

  find_package(MPI REQUIRED)
    include(CMakeForceCompiler)
    CMAKE_FORCE_C_COMPILER(mpicc ${CMAKE_C_COMPILER_ID})
    CMAKE_FORCE_CXX_COMPILER(mpicxx ${CMAKE_CXX_COMPILER_ID})
    CMAKE_FORCE_Fortran_COMPILER(mpif90 ${CMAKE_Fortran_COMPILER_ID})

Which works, but I can't find where the compile flags are coming from. It's not using CMAKE_Fortran_FLAGS_*, but it does change it's flags based on the build type. Anybody have any idea how to set the flags?

Hi,

How do we tell the project to use the compilers found by FindMPI? On the master branch, FindMPI has been modified to create MPI_<LANG>_COMPILER, etc.., but how does one then specify that it should be used rather than the CMAKE_<LANG>_COMPILER?
