cmake

CMake is an open-source, cross-platform family of tools designed to build, test, and package software using compiler-independent configuration files. It is basically the de facto build tool for C++.

• CMake is a meta-build system. It does not build the project directly; instead, it generates the native build scripts, like Ninja files, Makefiles, or Visual Studio solutions)

Commands

• cmake -S . -B build: The Configure step. -S . points to the source code; -B build creates a directory where the generated build files will live.
• cmake --build build: The Build step. This tells CMake to run the underlying build tool (like make or msbuild) to actually compile the code.
• cmake --install build: Moves the compiled binaries and headers to their final system location (e.g., /usr/local/bin).
