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 ?
