As such would this get much use unless it was integrated into these generators? May be worth approaching them to see if they have any requirements/observations about the option?


Having it integrated into e.g. cmake would be a great project for someone to take on, but for us (FreeBSD) it would be useful by itself. Our build is about 175K lines of hand-written Makefiles and we could plug it in with a small change in a couple of places. In any case we shouldn't hold up lld support waiting on prospective cmake changes IMO.
