No library needs to be built for iAVC. The file src/effects/AvcCompressor.cpp includes the iAVC files. While it is somewhat unorthodox to include a .cpp file, it does save building a library. Keeping the iAVC files in a directory of its own is appropriate and makes it easy to remember that iAVC is under LGPL license and not simply part of Audacity.
