Brief description of tool

Ninja is a small build system with a focus on speed. It differs from other build systems in two major respects: it is designed to have its input files generated by a higher-level build system, and it is designed to run builds as fast as possible.

The page about C++ Modules in the CMake documentation lists the following requirements:

Compiler

• MSVC toolset 14.34 and newer (provided with Visual Studio 17.4 and newer)
• LLVM/Clang 16.0 and newer
• GCC 14 (for the in-development branch, after 2023-09-20) and newer

Build System Generator

• Ninja
• Visual Studio 17 2022

---

The latest runner images all contain both CMake and a compiler that is capable to use C++20 Modules.
The images for Windows contain a capable build system.

The images for Mac and Linux are missing a capable build system. Adding Ninja solves that issue.
