 Tourmaline is by no means currently usable. The project is incredible volatile with constant changes and improvements. Please wait until a release is made.
 
 However if you cannot just help yourself you can compile a tourmaline demo by running
-g++ program.cpp -std=c++23 -lTourmaline -I/usr/local/include/TourmalineExternal -o program
