are a standardized way to share build configurations and settings through JSON files, eliminating the need for long, manual command-line arguments. They allow you to define everything from compiler toolchains to build directories in a format that both human developers and modern IDEs (like VS Code, CLion, and Visual Studio) can understand. 1.
