This has been fixed in [r27491](http://viewvc.slicer.org/viewvc.cgi/Slicer4?view=revision&revision=27491), a regression due to the change of VTK version from 9.0 to 8.2 …

I will delete the Windows nightly CDash entry and re-trigger a “nightly” build with that change, that way we will have a working windows package.
