You could try adding /opt/libmesh/include/mesh,
/opt/libmesh/include/geom (etc.) for every subdirectory where we have
include files (assuming you've already installed these files to
/opt/libmesh/), but I'd suggest instead using the Makefiles that we've
already set up with include paths, optimization compiler flags, etc.

Try "make link_examples" in the root libMesh directory", or "make" in
examples/ex0.
