[vtkusers] VTK with OpenVR on Linux (HTC Vive)

[Ken Martin]

You have to explicitly instantiate the OpenVR classes. Basically change

  vtkNew<vtkRenderWindow> renderWindow;

to

vtkNew<vtkOpenVRRenderWindow> renderWindow;

for renderwindow, renderer, interactor and camera.  Give that a shot.

Thanks!
Ken
