 An example of this would be the ``libdwarf`` build, which has one
 dependency: ``libelf``.  Every call to ``cc`` in the ``libdwarf``
 build will have ``-I$LIBELF_PREFIX/include``,

+``-L$LIBELF_PREFIX/lib``, and ``-Wl,-rpath,$LIBELF_PREFIX/lib``
 inserted on the command line.  This is done transparently to the
 project's build system, which will just think it's using a system
 where ``libelf`` is readily available.  Because of this, you **do
