Description
What do I want to do: create a widgets project with Qt Creator and run it on the IOS simulator.
When I created the test project I selected CMAKE and I selected the Qt 6.4.0 for iOS, Qt 6.4.0 for iOS Simulator and Qt 6.4.0 for macOS kits.
When I tried to compile this project targetting Qt 6.4.0 for iOS Simulator I got:

Right off the bat I should say that when I created the same type of project but I selected qmake, the whole thing worked fine and I was able to run the app in the simulator. The project also works with CMAKE when I targeted MacOS.
I tried to find more information about this error but none of the suggestions I found worked. Here is on post on SO, but I don't understand the answer. I tried different required versions of CMAKE but none of them worked.
Any idea about what's going on? What can I do to get it working? Imo, this is a basic starting point, app created with Qt Creator, uses CMAKE, targets iOS simulator, and I cannot get past the compilation phase.
