Consider FindMPI

[bobpaw]

When creating downstream projects that use PUMI, I regularly include the following lines:

find_package(MPI REQUIRED)
find_package(SCOREC 4 REQUIRED)
target_link_libraries(SCOREC::pcu INTERFACE MPI::MPI_CXX)

PUMI should consider using FindMPI instead of requiring -DCMAKE_C_COMPILER=mpicc -DCMAKE_CXX_COMPILER=mpicxx:

Or other clarify why it does not work.

I agree. Requiring mpi compiler wrappers was a hold over from when mpi was required.

Yes, it should also be added to the config file as a dependency.
