Hi!  
i try to use standalone ParaView main window and Custom App.  
i try to open PVD set of VTU files.  
But, when i try pqFileDialog, the plugin is abscent.  
The problem i think, Paraview initializing is  
InitializerT::Status status = pvInitializer.Initialize(argc, argv);  
but standalone app is just  
pqPVApplicationCore appCore(argc, argv);

`InitializerT` is part of the common client code written. Are you using the CMake infrastructure to create ParaView client applications?
