I got a warning about the 10.14 SDK not being installed, which I found surprising since I know I have the CLTs installed. Running the suggested "xcode-select --install" complains that the CLTs are already installed, and suggests Software Update, which doesn't do anything. Looking in the SDKs directory within the Xcode bundle, I see 10.15 but not 10.14, though that ought to work and seems to work. Perhaps the SDK check (which I think is separate from the port itself) is overly picky.
I don't know about qt6 specifically, but in the general case, the warning is precisely as picky as it should be. Building anything that doesn't handle weak-linked symbols correctly (which is most things) against an SDK newer than the OS it will be run on will result in runtime crashes. This is why we always say to install the Command Line Tools, because Xcode doesn't necessarily have the SDK matching the current OS version, whereas the CLTs do.
SDKs provided by the CLTs would be in /Library/Developer/CommandLineTools/SDKs. If you have a 10.14 SDK there but qt6 is not finding it, it may only be looking in Xcode, and hopefully it knows what it's doing.
