So, you want to use C++ Modules ... cross-platform?
summary
Shows that C++ Modules work cross‑platform but with caveats: msvc is broadly usable, clang 17 and GCC lag and show BMI consistency issues and crashes during modularization. CMake offers CMake 3.26+ experimental support relying on compiler dependency scanners; MSBuild already handles modules. Demo modularizes small (ar) and larger (SDL) header‑only libraries, builds on Linux with clang17 and on Windows with MSVC, and runs. Measured build speed for a full std header: include ~2s, header‑unit import ~15ms, named‑module import effectively ~0ms (modularized standard library speeds).
