CMake by Example

CMake is an open source cross-platform meta build system that works on Windows, macOS, Linux, and more. It is designed to bridge the gap between the platform-specific build tools such as Ninja, GNU Make, BSD Make, Visual Studio, and Xcode. You can read more about CMake on the official CMake.org website. CMake is best known for its unmatched popularity as the primary C/C++ build tool.
