I'm saying there isn't one (well, a hundred messages in and there are a handful at last :) ). Nobody is discussing what's new for instance. I'd be interested in the status of moc (isn't mentioned on the page).
Question should be "even with C++17?". Cmake has had moc and uic support for years now. The question is why they don't leverage the c++17 features to get rid of moc, ffs.
Why would Cmake eliminate the need for Qt's moc? Cmake is a build system/makefile generator. You don't generate c++ from form files or Qt-annotated C++ files out of magic.
