... yet they share the same set of top-level cmake modules... :-/

Which is not clean, because those CMakeModules should be provided by the
libs themselves (e.g. libyang should provide FindLibYANG.cmake)...

Yes.

And since they do share the same source tree, we really want to download
it only once:

    NETOPEER2_KEYSTORED_DL_SUBDIR = netopeer2

(similarly for the other two packages, of course).
