Summary

0014322: FindMPI.cmake does not produce a complete list of compile and link flags (-pthread missing)

Description

Openmpi produces the following

mpic++ --showme:compile
-I/usr/lib/openmpi/include -I/usr/lib/openmpi/include/openmpi -pthread

mpic++ --showme:link
-pthread -L/usr/lib/openmpi/lib -lmpi_cxx -lmpi -lopen-rte -lopen-pal -ldl -Wl,--export-dynamic -lnsl -lutil -lm -ldl

However, the regex code in FindMPI.cmake fails to pick-up flags that start with p.

Additional Information

To pick up flags starting with p I changed the following lines in FindMPI.cmake.

        # Extract include paths from compile command line
#ORIGINAL string(REGEX MATCHALL "(^| )-[Df]([^\" ]+|\"[^\"]+\")" MPI_ALL_COMPILE_FLAGS "${MPI_COMPILE_CMDLINE}")
          string(REGEX MATCHALL "(^| )-[Dfp]([^\" ]+|\"[^\"]+\")" MPI_ALL_COMPILE_FLAGS "${MPI_COMPILE_CMDLINE}")

        # Extract linker flags from the link command line
#ORIGINAL string(REGEX MATCHALL "(^| )-Wl,([^\" ]+|\"[^\"]+\")" MPI_ALL_LINK_FLAGS "${MPI_LINK_CMDLINE}")
          string(REGEX MATCHALL "(^| )-[pWl]([^\" ]+|\"[^\"]+\")" MPI_ALL_LINK_FLAGS "${MPI_LINK_CMDLINE}")
