Correct.  We need a way to activate such tests only on machines
where we expect them to work.  It would be nice to have something
better but I'm not sure what else we can do.  We used to try to
add tests for find modules automatically but that ends up needing
to run the find modules as part of configuring CMake, giving the
false appearance that CMake actually needs all those packages and
possibly breaking on bad ones.  The GTK2 tests still have this
problem.
