even after installing libopus from official repo, configure result show OPUS as no and audiobrige support is not built

[shivanshtalwar]

What version of Janus is this happening on? 1.2.1

Have you tested a more recent version of Janus too? yes Was this working before? no

Additional context I compiled dependencies on ubuntu 18 including libopus and also explicitly installed Opus from official repo and on running

./configure --prefix=/opt/janus

Please ask questions on the group, not here, as it's not a code issue (which is what we use github issues for). That said, most likely you either installed libopus in a location the configure script can't find it, or you installed the library but not the headers (the -dev/-devel package most repos ship).
