Summary

0014872: FindMPI.cmake finds MPI of different compiler

Description

On the machine I'm using here there are multiple compilers and MPI variants in the PATH:
More precisely ifort, gfortran and pgf90 in the PATH and each of them brings their own MPI wrappers (one could argue that this is already a bug of the system, but I'm not the admin...).
So without setting any additional environment-variables, cmake detects ifort as Fortran compiler and the MPI-wrapper mpif90 from PGI. As a result one obtains possibly strange compiler errors during make.
It would be helpful to get at least an error from cmake if the compiler ID (or version) of MPI_Fortran_COMPILER and CMAKE_Fortran_COMPILER differ...

Most probably the same effects could also occur for C / C ++, but I have not tested other languages than Fortran.

Steps To Reproduce

Install compilers from different vendors and a specific MPI variant for each them. Then put all compilers and at least one MPI variant in the path.
