Ninja is a small, fast build system designed to run builds as quickly as possible. It was created by Evan Martin while working at Google and is now widely used in various software development projects. Key features of Ninja include its speed, simplicity, and focus on performance. It generates a build graph from a high-level build system and executes builds based on this graph. Ninja is particularly efficient at incremental builds, only rebuilding what's necessary when source files change. Ninja uses a simple, human-readable file format to describe the build. It's designed to be generated by other build systems, serving as a low-level build system that can be used as a backend for higher-level build systems like CMake. The system is cross-platform, supporting Windows, macOS, and Linux. It's used in several ...
