Cloned Slicer master (b748b88cefa57bc126f3a5c64a4fb59c28e4bb9b) and tried to build with Qt 5.9.1.

Received many generation errors similar to:

```
  CMake Error at Libs/vtkAddon/CMakeLists.txt:94 (add_library):
    Cannot find source file:

      C:/d/Slcr/S4D/Slicer-build/Libs/vtkAddon/vtkAddonHierarchy.stamp.txt

    Tried extensions .c .C .c++ .cc .cpp .cxx .m .M .mm .h .hh .h++ .hm .hpp
    .hxx .in .txx

```

Has anyone else experienced this?

Edit: not suprising, but build errors follow on the form:

`CUSTOMBUILD : CMake error : CMake can not determine linker language for target: vtkAddon [C:\d\Slcr\S4D\Slicer.vcxproj]`

Most likely related to the VTKv9 update.

I submitted issue [17217](https://gitlab.kitware.com/vtk/vtk/issues/17217) to upstream VTK project and proposed a fix in [MR vtk/vtk#3794](https://gitlab.kitware.com/vtk/vtk/merge_requests/3794) (already added to Slicer fork of VTK).

This addressed issues I experienced on Linux.

Look like there are still some issues.

Here are some related references that will be helpful to debug:

It turns out that the hierarchy stamp file has been removed in latest VTK:

> <https://github.com/Slicer/VTK/commit/a8ada6f05b950d8df50e2f6c7427591064d10f17#diff-5ce2dfc7465c1fe39c43979d84de3629>

> Instead, just use the hierarchy file as an output.

This means the following Slicer file would have to be updated accordingly:

[https://github.com/Slicer/Slicer/blob/b748b88cefa57bc126f3a5c64a4fb59c28e4bb9b/CMake/vtkMacroKitPythonWrap.cmake#L149-L154](https://github.com/Slicer/Slicer/blob/b748b88cefa57bc126f3a5c64a4fb59c28e4bb9b/CMake/vtkMacroKitPythonWrap.cmake#L149-L154)
