 * For your own project folders, it is most convenient to put them into the hacklib/src folder. Then provide a CMakeLists file in this folder. For example: hacklib/src/YourProject/CMakeLists.txt. You need to re-run CMake manually after adding your project folder, it will not detect the new folder itself. The basic CMakeLists file is the following, add source files as neccessary to the ADD_LIBRARY command:
