Some further information, ignore the CMP0054 warning it is not triggered when the CMake Minimum Version is 3.1
When running FindMPI.cmake, I discovered that I had a spurious registry entry for an older version of MPI so mpiexec.exe was not being found. When I deleted this it found mpiexec.exe in C:/Program Files/Microsoft MPI/Bin/mpiexec.exe OK. I think the key for HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\MPI should still be there before the other registry keys. You definitely need the new lib and include paths. I was able to use FindMPI.cmake and just add in these paths manually. Hope this helps.
