You need an MPI C compiler. Find out its name. I'd expect b) to work if
you use the right name. Otherwise try ./configure --enable-mpi
MPICC=name_of_mpi_c_compiler

> c. configure --enable-mpi=/usr/bin/mpcc --prefix=/hpc/gmxmpc

"--enable-mpi=/usr/bin/mpcc" isn't recognized. Read ./configure --help
