We just tried to build some of the “Tutorial” examples included in VTK 9.0.(0/1) source .tar.gz from [vtk.org](http://vtk.org), and they don’t seem to work - (CMake reports `Unknown CMake command "vtk_module_config"`).  
On closer inspection of their CMakeLists.txt, these don’t seem to be adapted to the new CMake module structure of 9.x; their CMakeLists.txt still contains `VTK_USE_FILE`, and no `vtk_module_autoinit`. This also seems to apply to examples in other folders as well.

It’s not such a big thing since up-to-date examples are available at [lorensen.github.io/](http://lorensen.github.io/) - but I’m confused as to why this out-of-date examples folder is included in the source archive? Including examples _not compiling with the version of the vtk library they come with_ probably will confuse quite a few newbies (who might decide vtk is not for them when they can’t get it to compile/run?).

Edit: Seems there is a bug report about this already: [https://gitlab.kitware.com/vtk/vtk/-/issues/17711](https://gitlab.kitware.com/vtk/vtk/-/issues/17711)
