[Christopher Neal]

Yes! That is exactly what I was missing. It compiles without any issues now.

Thank you Utkarsh.

    Chris,
    
    Try changing CMakeLists.txt, changing the `find_package(ParaView .. )`
    and `target_link_libraries(..)` as follows:
    
        find_package(ParaView 4.1 REQUIRED COMPONENTS vtkPVPythonCatalyst vtkIOXML)
    and
         target_link_libraries(CFullExampleAdaptor vtkPVPythonCatalyst vtkIOXML)
