Build scdaq RPM in CI
We now build the scdaq RPM in the CI. The docker image is based on the cern/cc7-base image with additional packages to build it. (The dockerfile is at https://gitlab.cern.ch/scouting-demonstrator/scouting-docker-images/-/blob/main/dockerfile-scdaq-builder.)
One curiosity is that I needed to add -pthread
to the Makefile, which I don't fully understand. (Maybe @meschi or @pzejdl have an idea?)
