Hello
Download the Rack SDK
Export the environment variable (for me like this): export RACK_DIR=/home/felix/Downloads/Rack-SDK
Run make install
Open VCV Rack, and type "1080" in the module selection screen and the three modules should be there!
If this doesn't work, follow more detailed instructions a VCV Rack Plugin Development
For serious questions, please raise an issue in GitHub and I will respond asap
Feel free to use or modify this for any purpose, as long as you do not sell it or claim credit for developing it
