Could you build this?
No Creating a build system tailored to C++20 modules demands deep understanding of compiler-specific BMI (Binary Module Interface) compilation order, dependency graph discovery, and linker internals across GCC, Clang, and MSVC.
What it would actually take: Requires scanning C++ source files for module declarations/imports (P1689R5 format or custom scanner), computing a strict directed acyclic dependency graph, and coordinating two-phase compilation of module interfaces (.pcm/.ifc) before consumers. Must integrate deeply with system compilers (Clang, GCC, MSVC) and their distinct, evolving flag specifications for modules. High-level systems programming and compiler toolchain internals expertise are mandatory.
