I’m confused as to what’s going on in that error output. I’m not familiar with XRRenderEngine.exe, if it is a target in VTK, I don’t recall having seen it before. Otherwise, maybe it’s a target in some dependent project?
Also, I see vtkPVXRInterfaceHelper in the output, which only exists in ParaView, so that doesn’t look like just trying to compile vtk9.4.0.rc2.
@Ben Boeckel What makes you think there may be a missing link to VTK::RenderingVRModels?
