The XXX_autogen targets are implemented as utility commands, which means they always run, even if there weren't any changes. For the Ninja generator and Qt >= 5.15 we're taking a different approach: This commit adds custom commands that create XXX_autogen/timestamp files. Those custom commands have a depfile assigned that is generated from the depfiles that were created by moc. The XXX_autogen targets merely wrap the XXX_autogen/timestamp custom commands. Fixes: #18749
