From d154ae5b114a6a04acd17a83f6d59caa9ec1005a Mon Sep 17 00:00:00 2001
From: David Robillard <d@drobilla.net>
Date: Sun, 12 Oct 2008 06:47:11 +0000
Subject: Split OSC/HTTP/JACK dependencies from ingen into separate libraries
 so engine library doesn't have a link time dependence on liblo/soap/libjack.
 Preliminary Ingen LV2 code wrapper (not functional yet).
