Two questions about new module system

Yes I read these abstracts from the link few times but I can’t say that I understand what it is about. For now I don’t fully understand the problem and the solution as well. I don’t have enough knowledge yet to understand it.
I would very appreciate if you give something like copy-past example how to launch any of 2D VTK example, maybe this one

By the way is it ok that I don’t have vtkRenderingContextOpenGL2-9.0.lib in VTK 9.0 or I should recompile the VTK library?
