Some packages don't have a library associated with them. This is fine if it's found by pkg-config, but if we fall back to searching system directories, the package resolver wouldn't know to avoid looking for libs. We should add a header_only option to make this work.
(Sadly, this is a bit of a leaky abstraction, since you shouldn't have to care how a lib is implemented in order to use it, but that's life...)
