@bill From what I can see there is no longer a `VTK_QT_VERSION` variable:

```auto
vtkGUISupportQt_LOADED: 
We have GUISupportQt
VTK_VERSION: 8.90.0
VTK_QT_VERSION: 
VTKWikiExamples: Building Qt examples
CMake Error at /usr/local/share/cmake-3.13/Modules/FindQt4.cmake:1313 (message):
  Found unsuitable Qt version "5.12.0" from
  /home/amaclean/Qt/5.12.0/gcc_64/bin/qmake, this code requires Qt 4.x
Call Stack (most recent call first):
  CMakeLists.txt:150 (find_package)

```

I also built VTK with `VTK_GROUP_ENABLE_QT:WANT` and `VTK_GROUP_ENABLE_QT:YES`, `VTK_QT_VERSION` remains empty.

In looking at `VTK/Examples/GUI/Qt` only Qt 5.x seems to be supported.
