VTK modules are a layer on top of CMake targets for handling optional
dependencies, wrapping, autoinit, kit compiling, etc. They are indicated
via properties on targets and can be provided by any package. They don't
need to come from `find_package(VTK)` at all. VTK provides VTK's
modules. ParaView provides its modules, ITK would provide its modules.
VTK is special only in that it is the source for the module CMake API
and contains some things like the wrapping tools, core wrapping
libraries, etc.
