I will assume that the build process was similar to described at [1].
A quick look at so-called "sources", i.e. [2] reveals us:
1) Multiple *jar files of unknown content.
2) Pre-built *so files without sources, and without any visible
licences.
3) Build-dependency on non-free Oracle JDK and pre-built Apache ANT.
4) Possible (too lazy to check it) arbitrary file downloads during the
build process - ant in (in)famous for it.
Proper building from the source would require (some steps omitted for
simplicity):
1) Building openjdk from the source (Debian does it, so that's easy).
2) Building ant from the source (ditto).
3) Re-building all those *jar blobs (possible, given that those are
popular java libraries).
4) Re-building from the source all those *so files.
5) Fixing build.xml to prevent it from downloading random *jars from all
the Internet (may be impossible).
6) De-composing the resulting *jar(s) and replacing bundled *jars with
proper Debian dependencies.
And last, but not least:
7) Repeat build process once jitsi source is updated.
Points from 3 to 7 inclusive require one to be an "IT professional" IMO.
Somehow I doubt that aforementioned local member of LUG followed the
latter process, most possibly it was former. I.e. - not real BTS at all.
