What you need to build line yourself

readline library (should be already on your system, if not, you have to install it)
jack library (only for Linux. It is not installed by default. If the computer has no audio/music production sofware succefully used then a jack installation is needed)
CMake

To clone this repo with rtmidi and link submodules included

git clone --recursive https://github.com/pd3v/line.git

Build and run line yourself

(CMake is necessary)

Go to line's folder

In command-line, type each of the following + Enter:

./build.sh
cd build
