I already follow the instruction to build the Slicer inner-build folder in git bash or cmake gui, but it still comes out this error.

> [Documentation/Nightly/Developers/Build Instructions/Configure - Slicer Wiki](https://www.slicer.org/wiki/Documentation/Nightly/Developers/Build_Instructions/Configure#Windows)

> [Extensions — 3D Slicer documentation](https://slicer.readthedocs.io/en/latest/developer_guide/extensions.html#windows)

Now, I use cmake to configure the code in this link first.

> [GitHub - Slicer/Slicer: Multi-platform, free open source software for visualization and image computing.](https://github.com/Slicer/Slicer)

The build of this code is fine.

Second, I configure the code of this extension (SlicerVR)

> [GitHub - KitwareMedical/SlicerVirtualReality: A Slicer extension that enables user to interact with a Slicer scene using virtual reality.](https://github.com/KitwareMedical/SlicerVirtualReality)

I cannot find out the SlicerConfig.camke in all build folder including Slicer-master’s inner-build folder.

Is it have anything that I forgot to do?

`SlicerConfig.cmake` is in your inner Slicer-build folder, such as `c:\D\S4D\Slicer-build\SlicerConfig.cmake` if the file is not there then your Slicer build was incomplete. Check the error messages that you got during the build and resolve them. If you are not sure how then upload the complete build log somewhere and post the link here.

The SlicerConfig.cmake problem have been fixed.  
CMake build the SlicerVR 's inner build folder successfully, but it still has some error in building the ALL\_BUILD project.  
If I use Slicer v4.11 in github to build, then It comes out those error,

We are in the process of finalizing the update of VTK and also fixing the SlicerVirtualReality extension to account for these changes.

This should be completed in the next few days. Once completed, I suggest you give another try.

So it will be fine, if I change the VTK to other version, such as VTK8. Am I right?

I had the strangest problems on Windows 11 and @dgmato had other problems on his machine that he didn’t have with the previous VTK (the action manifest issue shown in the PR comments, that since then I had too). I want to reinstall the computer and try again, but I simply haven’t found the time yet.
