C++ components of 3D Slicer Qt Loadable Modules ([Module Overview — 3D Slicer documentation](https://slicer.readthedocs.io/en/latest/developer_guide/module_overview.html#loadable-modules)) are wrapped in python and exposed automatically (mostly). These wrapped python components will be available in Slicer and can be used by other modules.

I would recommend that you try to integrate this C++ code as part of a Loadable Module. It is also possible to have a sort of hybrid module, where Scripted module ([Module Overview — 3D Slicer documentation](https://slicer.readthedocs.io/en/latest/developer_guide/module_overview.html#scripted-modules)) can include some C++ components (an example of this approach is one of the modules of Slicer-Liver: [Slicer-Liver/LiverSegments at develop · ALive-research/Slicer-Liver · GitHub](https://github.com/ALive-research/Slicer-Liver/tree/develop/LiverSegments))
