CMake is a cross-platform build system generator that allows developers to write platform-independent build scripts. CMake uses a CMakeLists.txt file to define how the project should be built, including source files, libraries, and target executables.
The CMake build process can be broken down into the following steps:
1. Configuration: CMake reads the CMakeLists.txt file and generates platform-specific build files (e.g., Makefiles, Visual Studio projects).
2. Build tree generation: CMake creates a build directory and populates it with the generated build files. This directory is known as the build tree.
3. Build: The actual build process takes place in the build tree, using the generated build files.
During the configuration step, CMake detects the system environment and generates build files tailored to the specific platform. This allows developers to write a single CMakeLists.txt file that can be used on multiple platforms without modification.
Once the build files are generated, developers can use standard build tools (e.g., make, Visual Studio) to build the project. CMake provides a consistent interface for building projects across different platforms, making it a popular choice for cross-platform development.
