Summary: 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}")
