Summary: FindMPI doesn't find openMPI properly
Description:
find_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 Reproduce:
1. Install OpenMPI-1.6 (x86 or x64)
2. add find_package(MPI REQUIRED) to CMakeLists.txt
3. check MPI block of variables in cache
