missing vtkImageRenderManager and other headers

There is a folder(Rendering/Parallel) in the source code, but it doesn’t seem to have been compiled.
How can I make the compiled result contain the headers in this folder?

You can tell CMake you need this module by passing it -DVTK_MODULE_ENABLE_VTK_RenderingParallel=YES. There may be conflicts with other requests; the error messages should hint what they are.

Thank you! I didn’t find this option until I enabled “Advanced”. :smile: :smile:
