Depends on where you are.

VC++ and clang latest with MSBuild or CMake/ninja are there, minus some bugs or code completion misbehaving (but bearable).

GCC 16 is mostly ok now, also with CMake/ninja.

All my hobby coding in C++ makes use of modules, at work it is a different matter, where libraries to be consumed by Java/.NET/nodejs, are still using C++17 as baseline.

Note the CMake version was tested initially with clang 17, and we're already on clang 22, so some of those comments are irrelevant nowadays, I haven't bothered to update the project.

Naturally if you cannot be on latest compiler releases, or suffer from CMake phobia, the support isn't there.
