 We call this "virtual assignment", and can be specified by ``%virtual=provider`` or ``^virtual=provider``.

+We will now install HDF5 with MPI support provided by MPICH, ensuring that the C component of HDF5 is compiled with ``gcc``.
 We could use the same syntax for ``^mpi=mpich``, but there's no need because the only way for ``hdf5`` to depend on ``mpich`` is to provide ``mpi``.
 This is also why we didn't care to specify which virtuals ``gcc`` and ``clang`` provided earlier when building simpler packages.
