Compilation error with Qt5.15.12 on MacOS - problems with qglobal.h

[KFlck02]

I use Qt5 in combination with the Geant4 software as a visualizer. However, recently after building my project with CMake and C++ 17 standard, I receive the following shortened list of compilation errors (similar to the question posted here https://forum.qt.io/topic/150201/qglobal-h-391-11-error-maybe_unused-attribute-cannot-be-applied-to-types?_=1709828312588&lang=en-GB)

I am using Qt5.15.12 as installed from Homebrew on macOS Sonoma 14.3.1 (Xcode 15.2) and using AppleClang 15.0.0 for target arm64-apple-darwin23.3.0.
This is not an issue I have encountered before so any help would be appreciated.
