Summary: 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 Reproduce:
configure 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
