Summary:                    FindMPI doesn't work correctly on Windows with
OpenMPI 1.6.2
Description: 
The problem exists with older versions of OpenMPI as well. FindMPI.cmake raises
errors and fails to set includes paths and query mpi arguments correctly on
Windows.

Steps to Reproduce: 
* Build and install OpenMPI 1.6.2 (with shared libs). My configuration for
OpenMPI was: -DBUILD_SHARED_LIBS:BOOL=ON -DCMAKE_BUILD_TYPE:STRING=Release
-DOMPI_RELEASE_BUILD:BOOL=ON

* In a simple cmake program include FindMPI.cmake. Point the MPIEXEC cmake
variable to the installed mpiexec.exe. Cmake will not be able to determine the
other MPI parameters correctly e.g. include paths are setup as quoted strings,
doesn't find mpicc, mpicxx, and mpi libs or MPI_C_COMPILE_FLAGS etc.
