Summary0009325: Under Os X, FindMPI.cmake use regex that Os X don't seem to recognize
Description# Extract linker flags from the link command line
string(REGEX MATCHALL "-Wl,([^\" ]+|\"[^\"]+\")" MPI_ALL_LINK_FLAGS "${MPI_LINK_CMDLINE}")

when adding those two lines
     message("${MPI_LINK_CMDLINE}")
     message("${MPI_ALL_LINK_FLAGS}")
MPI_LINK_CMDLINE = -fexceptions -lmpi_cxx -lmpi -lopen-rte -lopen-pal -lutil
but MPI_ALL_LINK_FLAGS is empty, it leads to an error when adding dependancies to a project
set_target_properties(project PROPERTIES LINK_FLAGS ${MPI_LINK_FLAGS})
Steps To Reproduce
Additional InformationEvery other regex in FindMPI seems to work fine.

Here is a hack to get around this problem,

First : On Mac OS X, OpenMPI is preinstalled in /usr/include and /usr/lib so mpiCC -showme:compile does not contain any include directory and the include files are accessible throught the PATH. So in order to have a valid MPI_INCLUDE_PATH simply add at line 151 :

list(APPEND MPI_INCLUDE_PATH_WORK " ")

The last line is realy a hack and may produce strange behavior. Second modify the regular expression at line 193 :

string(REGEX MATCHALL "-Wl|-l,([^\" ]+|\"[^\"]+\")" MPI_ALL_LINK_FLAGS "${MPI_LINK_CMDLINE}")
