[vtk-developers] Correct packaging of Tcl/Python/Java wrappers

[David Gobbi]

Hi Stephan,

As far as I understand, VTKTargets.cmake has no dependencies.  It is just a
list of targets that cmake produces at configuration time.  Those targets
only become dependencies when they are used in build rules.

When you try to build a C++ project against VTK, does the build actually
fail if the bindings are missing?
