• Follow building from source link I had to change the dependencies:

sudo apt-get install python-setuptools python-rosinstall ipython libeigen3-dev libboost-all-dev doxygen libopencv-dev ros-melodic-vision-opencv ros-melodic-image-transport-plugins ros-melodic-cmake-modules software-properties-common libpoco-dev python-matplotlib python-scipy python-git python-pip ipython libtbb-dev libblas-dev liblapack-dev python-catkin-tools libv4l-dev 

• You can now build with caktin build

• In addition, to run the calibration I had to install python-igraph:

Getting started with Juce on Ubuntu 18.04

1. Download Juce for linux here
2. Extract juce-5.X.X-linux.zip (I have it in /home/jokla/software/juce-5.4.7-linux)
3. Run the application from terminal with $ ./home/jokla/software/juce-5.4.7-linux/JUCE/Projucer or double-click on Projucer.
4. Follow this guide. I add to set up manually the path to Juce, the Juce modules and to Clion
5. Now install libwebkit2gtk-4.0-dev from a terminal with sudo apt-get install libwebkit2gtk-4.0-dev
6. You will need to install ladspa-sdk to build extras/AudioPluginHost/
