Comment:

 I just realise that this auto-detection will be executed for all MPI
 implementations, not just for OpenMPI. These may not support these command
 line options, although an executable mpic++ will exist. Therefore, instead
 of checking whether mpic++ is executable, we need to check the return code
 of calling mpic++ with these options, and/or check whether the result is
 empty or an error message.
