[vtk-developers] QVTKWidget - Error: no override found for 'vtkContextDevice2D'

[David Gobbi]

It's due to the addition of the VTK Rendering/ContextOpenGL directory
that occurred a couple weeks ago in the following commit:

http://vtk.org/gitweb?p=VTK.git;a=commit;h=c5121871

Basically, now that the OpenGL override for vtkContextDevice2D has been
moved int Rendering/ContextOpenGL, you have to make sure that you link
to vtkRenderingContextOpenGL.  See the following wiki page for more info:
