I am trying to add a python shell in my custom application like in the ParaView Client application.  
How can I configure my CMakeLists.txt? I have added the following

```auto
target_link_libraries(paraview_clone1
    PRIVATE
      ParaView::pvpythonmodules
      ParaView::pqPython
      ParaView::PythonInitializer)

```

but I get this error on build

```auto
ParaViewMainWindow.cxx:118:3: error: use of undeclared identifier 'pvpythonmodules_load'
  pvpythonmodules_load();
  ^
1 error generated.

```

Thanks

You should use `paraview_client_add` to make a client.

Is there a `pvpythonmodules.h` around? What are its contents?
