Boilerplate for Activating CMake Experimental Support for C++ Modules

This repository contains a CMake script boilerplate for activating CMake's work-in-progress support for C++ Modules (requiring C++20 or later). I put it here so I can conveniently reference it (via git subtree) in git repos. It comes with abolutely no warrantee whatsover. The original source is CMake's in-development documentation. Special thanks to Ben Boeckel for helping me with the right set of incantations. All bugs and errors are mine.
