yes you have CPM, vcpkg and conan, but those are not really standard and there is friction involved in getting it work.
Once big companies like Google started pulling out of the committee, they lost their connection to reality and now they're standardizing things that either can't be implemented or no one wants as specced.
Neither of those things require modules as currently defined.
Personally I use them in new projects using XMake and it just works.
There's not a compatible format between different compilers, or even different versions of the same compiler, or even the same versions of the same compiler with different flags.
This seems immediately to create too many permutations of builds for them to be distributable artifacts as we'd use them in other languages. More like a glorified object file cache. So what problem does it even solve?
They have effectively zero use outside of hobby projects. I don’t know that any open source C++ library I have ever interacted with even pretends that modules exist.
