CMake issue running 'pip install pybgs' on Ubuntu

Hello,

We are running into trouble when trying to pip install pybgs, getting the following error:

Apparently, there are no No SOURCES given to target: bgslibrary_core.

We are using a containerized Ubuntu version. I have included our Dockerfile for reference. We have 'build-essential', 'libopencv-dev' and 'python3-opencv' installed inside of our container, so all dependencies seem to be in place.

I have attached our Dockerfile (remove the .txt before running docker build) for reference.
