Summary0013478: FindMPI doesn't find openMPI properly
Descriptionfind_package(MPI ...) doesn't define all necessary variables correctly with openMPI-1.6 and older on windows7:
- MPI_{LANG}_INCLUDE_PATH contains ';' instead of ' '(spaces), for example: "C:\Program;Files;(x86)\OpenMPI_v1.6-x64/include". But this isn't all, to fix this variable i must add ';' to the front and to the back of string (for this working result: ;"C:\Program Files (x86)\OpenMPI_v1.6-x64/include"; ) .
- MPI_LIBRARY and MPI_EXTRA_LIBRARY aren't found automatically.

OpenMPI bin directory was added to environment. Command "mpicxx --showme" has output:
"cl.exe /I"C:\Program Files (x86)\OpenMPI_v1.6-x64/include" /TP /EHsc /DOMPI_IMPORTS /DOPAL_IMPORTS /DORTE_IMPORTS /link /LIBPATH:"C:\Program Files (x86)\OpenMPI_v1.6-x64/lib" libmpi_cxx.lib libmpi.lib libopen-pal.lib libopen-rte.lib advapi32.lib Ws2_32.lib shlwapi.lib"

Other commands such as "mpicxx --showme:incdirs" have correct output too.
Steps To Reproduce1. Install OpenMPI-1.6 (x86 or x64)
2. add find_package(MPI REQUIRED) to CMakeLists.txt
3. check MPI block of variables in cache

Moving to backlog because FindMPI has no module maintainer:

 http://www.cmake.org/Wiki/CMake:Module_Maintainers [^]

If anyone wants to look at fixing this the problem is probably here:

 http://cmake.org/gitweb?p=cmake.git;a=blob;f=Modules/FindMPI.cmake;hb=v2.8.9#l291 [^]

where the module parses the command line from the showme. The regular expressions used may not be working in this case. Once could use the separate_arguments command instead:

 http://www.cmake.org/cmake/help/v2.8.9/cmake.html#command:separate_arguments [^]

with either the UNIX_COMMAND or WINDOWS_COMMAND option.
