Yeah, without the `vtkRenderingContextOpenGL2` library, you’ll have to drop the `vtkRenderingContext2D_AUTOINIT` line.

If you’re not using CMake, you’ll have to do what `vtk_module_autoinit` is doing for you manually. That is described in [this section](https://vtk.org/doc/nightly/html/group__module.html#module-autoinit).
