Don't want compile on MacOS 15.7.3

[axonde]

Have a problem when try to compile the project with

mkdir build
cd build
cmake ..
make

Actually, the error happens when the make command is touched:

I'm sure that this is related to new Clang compiler: i used Ventura AppleClang in the past, all works (but no CI was created hwvr to proove that?), and now I suddenly changed version by switching to new macOS (on Sequoia currently).

C++ apple compiler is not legacy-support anymore?
No, i think i've used an old hack which don't work now ;)

Will try to fix that when I'll have time
