Description
Use case:
Fortran language support is on - but MPI Fortran support is not needed.
I think because BLT calls find_package(MPI REQUIRED) we will always hit an error:
49 -- Found MPI_C: /lib64/libxpmem.so (found version "3.1")
50 -- Found MPI_CXX: /lib64/libxpmem.so (found version "3.1")
51 -- Could NOT find MPI_Fortran (missing: MPI_Fortran_WORKS)
>> 52 CMake Error at /usr/tce/backend/installations/linux-rhel8-x86_64/gcc
-8.3.1/cmake-3.24.2-ywx52e32uh6gkxzuyubpwkulzgdvxyh6/share/cmake-3.2
4/Modules/FindPackageHandleStandardArgs.cmake:230 (message):
53 Could NOT find MPI (missing: MPI_Fortran_FOUND) (found version "3.
1")
For this case, the following would work:
find_package(MPI COMPONENTS C)
But we need to find the right way to wire as a blt option.
