Hi,  
I wrote a plugin, which delivers a filter in C++. Now I would like to wrap my plugin with python. My file-structure looks like this:

- CMakeLists.txt
- Plugin
  - paraview.plugin
  - CMakeLists.txt
  - Filter
    - CMakeLists.txt
    - vtk.module
    - Filter.xml
    - Filter.cxx
    - Filter.h

I tried to wrap my vtk module with python too using the following Plugin/Filter/CMakeLists.txt:

```
set(classes
  Filter)

vtk_module_add_module(VTK::CustomFilters
  CLASSES ${classes})

paraview_add_server_manager_xmls(
  XMLS Filter.xml)

vtk_module_wrap_python(
  MODULES VTK::CustomFilters
)

```

How should I do it correct?

`vtk_module_wrap_python` needs to be called from the same level as `vtk_module_build`. That is when the modules have all of the relevant information attached to them (headers, dependencies, etc.) that is used by the wrapping code.
