cmake‑zig is a CMake extension that lets C/C++ projects build and link Zig libraries as native static or shared modules. It provides `find_zig` and `add_zig_module` functions that locate the Zig toolchain, map CMake build types to Zig optimization modes, and automatically handle target‑triple detection and cross‑compilation, making it useful for developers who want to integrate Zig code into existing CMake‑based builds.
