[Freeswitch-users] Disable speex for build?

I’m doing a custom build of FreeSWITCH, pretty stripped down. I’ve been able to skip building most things, but I don’t see a way to disable the requirement for libspeex/libspeexdsp. I did poke around configure.ac a bit for clues, but didn’t see any. Is there a way to disable building with speex support? Chad
