A buildsystem maintainer might decide that he simply wants to provide the 
normal Foo_LIBRARIES variable to its users, so they can simply continue to use 
it as they always did, and don't have to care about the new cmake features.
I don't say whether that's a good or bad idea, but it's possible and IMO not 
too far fetched.
