Please be sure to add the $SU2_HOME and $SU2_RUN environment variables, and update your $PATH with $SU2_RUN

there is no problem! as i configure with ./configure --with-CGNS-lib=/usr/local/lib --with-CGNS-include=/usr/local/include --with-Metis-lib=/usr/local/lib --with-Metis-include=/usr/local/include --with-Metis-version=5 --with-MPI=/usr/local/bin
i got the output

The versions are mpich-3.0.4, cgnslib_3.1.4-2, metis-5.1.2, what is the matter???

When you specify the MPI option, you need to have the compiler specified, e.g.:

--with-MPI=/usr/local/bin/mpicxx

nice answer
