In case anyone is interested, here are the steps I’ve followed to build CasparCG server v2.3.0 LTS for Ubuntu 20.04. The build is done inside Docker container so as not to pollute your system.
WARNING: This is work in progress, so some things may not work.
docker run -it --name casparcg nvidia/opengl:1.2-glvnd-devel-ubuntu20.04 /bin/bash

If everything went well, you should have server v2.3.0 LTS built inside the server folder. You might need to install a few missing packages (eg, libsfml-graphics2.5) on your system, if it fails to run.
NB: This version of the server uses native boost and ffmpeg packages.
