The build process uses the mpic++/mpicxx/mpiCC compiler wrapper, which
then inserts the correct "-I"/"-L" switches for the real C++ compiler.

The build process searches for "mpic++", "mpiCC" and "mpicxx" in this
order; look into `tools/build/v2/tools/mpi.jam` for details.

If you want to force the use of a specific `mpic++`, you can append
this line to the `user-config.jam` file:

    using mpi : /path/to/preferred/mpicxx ;

Best regards,
Riccardo
