Yes, CMake verifies targets that are created. Those with non-existant
LOCATION values are errors. The `-devel` package should require
everything.

Alternatively, if the wrapper libraries aren't meant to be linked to
directly, we can skip exporting them to VTKTargets.cmake in the first
place. We could also create different export sets for each language
binding.
