<p class=MsoNormal style='margin-bottom:12.0pt'>It will search standard
locations (/usr/include & /usr/lib) for the headers and libs. Set
MPI_LIBRARY and MPI_INCLUDE_PATH if it doesn't locate them for you
automatically. The FindMPI module does interrogate the mpicc compiler for some
of this information but I am not sure if that is the case on Windows.<o:p></o:p></p>
