Hey everybody,

Caused by troubles with ALSA on Ubuntu, i want to try out real-time esttings with JACK.

I disabled all audio-devices exept JACK in the Projucer and installed the latest library with `sudo apt-get install ack-jackd2-dev`  
I even looked up in `/usr/include/` for `jack/jack.h` and its existing.

But I still receive the error `'jack/jack.h' file not found` in `juce_audio_devices.cpp`.

Is it necessary to include the `/usr/include/` by manually?

Thanks for your ideas
