so far, I used gbp buildpackage together with Cowbuilder. However, I cannot
figure out how I am expected to build a package that would depend on
another package which is not in the distribution. In my case: qml mapboxgl
would depend on mapboxgl, but the latter is also build locally. this is
something that OBS makes rather simple through the use of the repositories
which are served from the build farm directly.

[... PPA -> got it, staying away for now from PPA ]

Thank you very much! I am sure that all of you are very busy right now.

have to get artifacts from the web (and install manually).

In this respect, I will mainly focus on using Flathub right now which has
such fully automatic system available and which should be compatible with
L5.

Thanks, I'll check these and see if I comply with it as well.
