Hi Zaak, When using CMake, it's generally best to use the actual compiler rather than any compiler wrappers (with Cray being the exception). Given that, set the CC, CXX, and FC environment variables to the actual compilers you want to use and then the MPI_{C,CXX,Fortan}_COMPILER CMake variables the MPI wrappers. FindMPI will then interrogate the MPI wrappers to extract the appropriate include and link options.
