This variable is set to allow the use of the nice ParseAndAddCatchTests script in the case where a launcher is needed to execute the script. This is introduced to allow to launch unit tests using mpi. In this case one can write for instance set(OptionalCatchTestLauncher ${MPIEXEC} ${MPIEXEC_NUMPROC_FLAG} ${NUMPROC}) before calling the ParseAndAddCatchTests function.
