Sorry, but it doesn't. 

I replaced the directory GUISupport/Qt from 5.6.0 with the one from git,
and I got many errors like this:

VTK/GUISupport/Qt/QVTKGraphicsItem.h:36: error: forward declaration of ‘struct vtkGenericOpenGLRenderWindow’

Do I have to download all vtk files from git repository to compile the
new QVTKWidget2 ?
