 `setup-cpp` is supported on many platforms. It is continuously tested on several configurations including Windows (11, 10, 2022, 2019), Linux (Ubuntu 22.04, Ubuntu 20.04, Fedora, ArchLinux), and macOS (12, 11, 10.15). `setup-cpp` is backed by unit tests for each tool and integration tests for compiling cpp projects.

 `setup-cpp` is **modular** and you can choose to install any of these tools:

 `setup-cpp` automatically installs the dependencies above tools if needed for the selected tool (e.g., `python` is required for `conan`).
