[vtkusers] Weird Problem with OpenVR SDK

[Ken Martin]

Have you set

# This option determines if the VR rendering code will become
# the default renderer
option(VTK_OPENVR_OBJECT_FACTORY
  "Make openVR the default render window for VTK" ON)

to off? Otherwise the factory mechanism will always try to create the
openvr classes.
