You have to specify -I/install/directory/include in CFLAGS and CXXFLAGS and
-L/install/directory/lib in LIBS.

If you use static libs (that's the default for SuiteSparse, then this
suffices, but beware that CHOLMOD needs also -lmetis to work, which
Octave's configure script doesn't try). I've worked this around by
modifying SuiteSparse so that libmetis.a is included in libcholmod.a.
