As an enhancement it'd be nice to add a '--enable/disable-examples' argument so
that we keep the ability to build this without needing libvirt available. Indeed
if we make it optional, there's no reason not to use libvirt-gobject for the
example programs - only the library needs to avoid a libvirt/libvirt-gobject
dependency.
