I’m trying to build VTK from the source on Windows with three modules enabled. I got the source from [here](https://github.com/Kitware/VTK) and I’m enabling VTK::RenderingOpenGL2, VTK::RenderingOpenVR, and VTK::RenderingOpenXR.
The building process I followed used these commands:
```auto
cmake -DVTK_MODULE_ENABLE_VTK_RenderingOpenGL2=WANT -DVTK_MODULE_ENABLE_VTK_RenderingOpenVR=WANT -DVTK_MODULE_ENABLE_VTK_RenderingOpenXR=WANT -DOpenVR_INCLUDE_DIR:PATH='...' -DOpenVR_LIBRARY:FILEPATH='...' -DOpenVR_INCLUDE_DIR:PATH='...' -DOpenVR_LIBRARY:FILEPATH='...' -S . -B build
```
This configures the project and after this, I simply run:
```auto
cmake --build build
```
After about 40 or so minutes, the build completes, however, inside `build\lib\Debug` I don’t see any library from either of these modules. For example, for OpenGL, I was expecting `vtkRenderingContextOpenGL2-9.3d.lib`.
What is the problem here?

Are you building on Windows ?
Does `...` Works on windows ?
Please share the complete compilation output.

I’m building on Windows. Sorry, I should have mentioned that I put the correct paths in the real command. Here, I have placed `...` for convenience. Compilation works successfully, however, `.lib` files for OpenGL, OpenVR, and OpenXR are not generated under the `lib` folder inside the `build` folder.

Please share the recursive content of `lib` and `bin` directory.

Looks fine on my own build.
Please start from scratch and share the output of the cmake configuration of VTK.

Here is the log of configuring the build with CMake: [configlog.txt - Pastebin.com](https://pastebin.com/zTjcfJfH)
I built it again after this and the same issue is happening.

try with `-DVTK_MODULE_ENABLE_VTK_RenderingOpenGL2=YES` ?

Same issue. What could be causing the build to not generate libraries for OpenGL, OpenVR, and OpenXR even though the configuration happens correctly (I believe according to the logs I shared)?

I’m afraid I have no idea. It is working well here. Maybe try with ninja instead of visual studio ?

Using the `Ninja` generator is definitely recommended. You can also debug the module system with `-DVTK_DEBUG_MODULE=ON -DVTK_DEBUG_MODULE_ALL=ON`.
Note that the VS build may have a slight non-standard layout in the build tree. However, I see their `-hierarchy.txt` files, so they _are_ enabled. Did the build complete successfully? It seems that there’s probably a build failure somewhere.
