The /cmake folder and CMakeLists.txt file within the /output-native folder are required to build the project. The README.md file contains instructions to get the code up and running on each platform. Building the project isn't necessary to work through the porting process. The process for installing the required dependencies and getting the project to build successfully on your platform can be time-consuming and complex. If you still wish to proceed, you can build the executable through VS Code's Task feature by selecting Tasks | Run Task... from the menu and selecting Build Executable from the list after following the instructions in the README.md file.
