Zoltan Puskas 3074c0cafa sci-libs/opencascade: Fix broken build with USE="vtk -tk" 
For projects that do want TKIVtk (the core VTK visualization toolkit)
but don't need or want TKIVtkDraw (e.g. that have their own GUI
framework like Qt or GTK) we want to enable builds with just VTK
enabled and not force also installing TK.
