[Interest] [OS X] 10.12 SDK breaks qt5-qtconnectivity build (on 10.11)

[Samuel Gaist]

Hi,

I did too but I haven’t had the time to do a thorough analysis of what has changed exactly from 10.11 to 10.12 however if interested I have a small patch that adds the missing imports/includes where needed. It might need some cleanup though.
