If I run /home/user/builds/build-Slicer_src-Desktop-Debug/Slicer-build/bin/./SlicerApp-real --additional-module-paths /opt/SlicerRT_bld/inner-build/lib/Slicer-5.9/qt-scripted-modules /opt/SlicerRT_bld/inner-build/lib/Slicer-5.9/qt-loadable-modules /opt/SlicerRT_bld/inner-build/lib/Slicer-5.9/cli-modules --no-splash --verbose-module-discovery
the GUI pops up, but with some warnings:

and DICOM import and many other things are not working.
This looks very similar to 2018-10-15 Windows nightly build "unable to import VTK" so maybe @jcfr has an idea on what’s happening.
