[CMake] configure_file: escaping (single) quotes

[CHEVRIER, Marc]

Yes, you have to rewrite your line as:
CMD="mpirun -n @MPIEXEC_PREFLAGS@ @MPIEXEC_NUMPROC_FLAG@ @MPIEXEC_MAX_NUMPROCS@ @MPIEXEC_POSTFLAGS@"

Objet: Re: [CMake] configure_file: escaping (single) quotes

The problem comes from CMake evaluating variable VAR (i.e. expression ${VAR…}) and detect wrong syntax.
The solution is to specify option @ONLY to command configure_file to avoid ${} evaluation.

The line after VAR is something like:

VAR="${VAR//'#'/}"

CMD="mpirun -n ${MPIEXEC_PREFLAGS} ${MPIEXEC_NUMPROC_FLAG} ${MPIEXEC_MAX_NUMPROCS} ${MPIEXEC_POSTFLAGS}"



I need MPIEXEC_* to be replaced. So, I need to use @ONLY and set all MPIEXEC variables with @ (but not $). Correct ?
