Try regular compiler when no MPI compiler.
If FindMPI can't interrogate any of the available compilers, it attempts to compile simple MPI programs with CMAKE_${lang}_COMPILER. If this works, it uses that as MPI_${lang}_COMPILER. This allows MPI to be discovered on Cray XT/XE systems, where modules are used and cc, CC, and ftn compilers *are* MPI compilers.
