forked from bartvdbraak/blender

Added new build option WITH_JACK_DYNLOAD for CMake and WITH_BF_JACK_DYNLOAD for SCons, which means there'll be no build-time linking against libjack and getting symbols from libjack will happen runtime using dlopen and dlsym tricks. Alternative would be to use weak linking, but it'll require having wrapper for preloading libjack. This new options are disabled by default and they only intended to be used on linux. Other platforms shall not be using this and there shall be no functional changes on non-linux platforms at all.
