qmake for Qt 5.15.15 fails on macOS Ventura 13.6 with Xcode 15.0

On macOS Ventura 13.6 with Xcode 15.0, qmake doesn't work even for a simple hello world app. I keep noticing the following error message

{{Project ERROR: failed to parse default search paths from compiler output
13:55:34: The process "/Users/xyz/Qt/5.15.15/clang_64/bin/qmake" exited with code 3.
Error while building/deploying project abc (kit: Desktop Qt 5.15.15 clang 64bit)
When executing step "qmake"}}

Switching to cmake works, but it would be useful to work with qmake with existing projects.
