A small CMake helper for C++20 modules (including C++23 import std)
I’ve been experimenting with C++ modules across different compilers and build systems, and ended up writing a small CMake helper script that makes the whole thing much less painful.
It doesn’t try to reinvent module support — it relies on CMake’s native named-module features and only adds a thin layer of convenience (shorter target definitions, optional header-unit helpers, and clean presets for Clang/GCC/MSVC).
If you’re playing with modules or want a minimal, practical setup without extra tooling, you might find it useful:

It includes example programs, compiler compatibility notes, and a summary of what actually works in practice on Windows/Linux.
