I am still getting the same error message. Also, if I want to build ParaView master with the OpenGL2 backend, do I need to set anything beside VTK_RENDERING_BACKEND:STRING=OpenGL2 ? I tried that and (after turning off some PV plugins) it starts building but then dies with

[ 74%] Undefined symbols for architecture x86_64:
