I have no idea how to build this ros package in my catkin_ws

edit

Hi, I'm new to ROS. I am currently using ros-melodic and had build several packages using catkin_make in my catkin_ws. Usually, I would just download the file from Github and paste it into the /src of my workspace and just catkin_make it. But now, I have stumble upon a file in Github : https://github.com/jmaye/pure-pursuit... and have no idea how to build it because I am unfamiliar with the directory and the CMakeLists.txt. I know it have something to do with cmake-make, but how do I do it without affecting other packages in my catkin_ws. If any further detail is needed to answer this, please let me know. TQVM.
