I’m trying to build VTK for emscripten and was able to do so successfully. Now I would like to test my build using the cone example listed here:  
[https://gitlab.kitware.com/vtk/vtk/-/blob/master/Examples/Emscripten/Cxx/Cone/README.md](https://gitlab.kitware.com/vtk/vtk/-/blob/master/Examples/Emscripten/Cxx/Cone/README.md)  
When I do:

```auto
emcmake cmake \
  -G Ninja \
  -DVTK_DIR=/work/build-vtk-wasm \
  /work/src/Examples/Emscripten/Cxx/Cone

```

I see the error:

```auto
CMake Error at /work/build-vtk-wasm/vtk-config.cmake:1 (include):
  include could not find requested file:

```

Is `vtl_module_autoinit` an outdated command? If so I’d like to find an example that used updated code so I can start using VTK.

That’s not the “real” error. That command would appear if this include had worked:

Does any other `vtk-config.cmake` file exist in the build tree?
