CMake is an open-source build automation tool widely used in software development for managing the build process in a platform-independent manner. It generates build files (such as Makefiles or Visual Studio project files) based on a simple scripting language designed to describe the build process abstractly. Developers define their project's structure, dependencies, compiler settings, and other build configurations using CMake scripts, which are then processed to generate native build environments for different platforms and IDEs. This approach allows software projects to be developed and built seamlessly across various operating systems and development environments, including Unix/Linux, macOS, and Windows. CMake simplifies the complexity of building and compiling software by providing a unified interface to create and manage build configurations, ensuring consistency and reproducibility across different systems. It supports a wide range of programming languages and integrates well with popular build systems and IDEs, making it a preferred choice for projects requiring efficient and flexible build management solutions.
