Summary0015942: regexpr in FindMPI.cmake filtering MPI_COMPILE_FLAGS fails for Intel-flag "-fp-model"
Description
FindMPI.cmake fails to filter the keyword required for Intel´s compile flags "-fp-model".

example:
icpc -O2 -xHost -ftz -fp-speculation=safe -fp-model source -Wl,-rpath-link=/usr/local/software/jureca/Stage1/software/Core/pscom/5.0.45-1/lib

returns -ftz -fp-speculation=safe -fp-model
instead of -ftz -fp-speculation=safe -fp-model source

reason:
any word not starting with -D or -f is skipped by regexpression in line 294
string(REGEX MATCHALL "(^| )-[Df]([^\" ]+|\"[^\"]+\")" MPI_ALL_COMPILE_FLAGS "${MPI_COMPILE_CMDLINE}")
Steps To Reproduceconfigure mpi, that mpicxx -showme:compile (for openmpi and openmpi derivatives) or mpi -compile-info (for mpich and mpich derivatives) includes the flag "-fp-model source"

include find_package(MPI) and check MPI_CXX_COMPILE_FLAGS

configure MPI to use
 -fp-model=source
or
 -fp-model "source"
seems to work with the Intel Compiler Suite 15.0,
but it is not the offical syntax: https://software.intel.com/en-us/node/525039 [^]
