Hm okay. I just tested with

```auto
curl -LO https://www.vtk.org/files/release/9.0/VTK-9.0.1.tar.gz
tar xf VTK-9.0.1.tar.gz
cd VTK-9.0.1/
mkdir build
cd build
cmake -DVTK_MODULE_ENABLE_VTK_RenderingContextOpenGL2=YES ..

```

and I’m not getting that warning here. Full transcript here: [transcript.txt](https://discourse.vtk.org/uploads/short-url/7syuxChBKqrsfYMwACk7RXpWS7l.txt) (30.0 KB)

Maybe it has something to with what groups/modules get enabled by default on your system. Would help to see the output from the CMake run.
