Description
I tried to move from Qt 5.7.0 to 5.9.3, everything was fine with the old one but there are some weird linker issues with the 5.9.3. Mainly with references from "libqios.a"
Classes like QIOSBackingStore or QIOSIntegration seems to be undefined. Indeed, I can find the sources for these classes on internet (.mm Objective C++ sources) but there's not any library like "libqiosbackingstore.a" for exemple. Are they really missing or are they built in libqios.a and this is another problem.

I noticed that there are some lib that are still here on Windows Qt 5.9.x (like Qt5DBus) but are missing on iOS.
