Dear Developers and Users

I have packages that use CMake to compile and install them. I did the steps of building them independently on Ubuntu 20.04 with commands such as **cmake** and **make** successfully. Also I built 3DSlicer as mentioned in [Build Instructions — 3D Slicer documentation](https://slicer.readthedocs.io/en/latest/developer_guide/build_instructions/linux.html) successfully.  
At now I want to add these packages to 3DSlicer so that they can be built while doing the building process for 3DSlicer.

Please guide me to doing it.  
Best regards.
