* Setup build on OS X

* Install Qt5 on OS X

* Install Qt5 on OS X / set path for CMake to find it

* Add deps on libarchive libsndfile jack liblo and cppunit

* libarchive needs to set PKG_CONFIG_PATH to be found

* Add paths for libarchive / Remove unwanted OSC

* ALSA is Linux only

* Use libtar instead of libarchive

* Use libtar by default on OS X

* Add lrdf / LADPSA to OS X

* LRDF does not drag LADPSA with brew
