Hi @BrodyHiggerson , fastbuild do have more support for cmake generator usage, but as fastbuild author's written ,it followed "dev" -> Perforce -> "master" development model ,github didn't update frequently (except new version published) , there's still some changes needed for fastbuild pending . cmake itself also changed a lot . since my last try, I've found cmake's qt moc function create same output file even in different configs, which can't work with fastbuild easily . cmake changed to create per-config outputs in recent versions,but unforunately this change also breaks fastbuild generator code (since my last try). Seems that there isn't too musch interests from both sides, so I give up this .
