Hmm, I don't think we should move away from frameworks on Mac OS.

As Morten mentions, these sysroots [1] still contain Frameworks for any 
API provided by Apple:

...

Plus ofc other system libs:

Regarding the installation path, /Library/Frameworks makes more sense 
than /usr/local/Qt to me. What's the benefit of switching that?

We might also investigate creating an overlay-SDK for mac, which appends 
the base SDK (sysroot). This can be used in Xcode through the 
ADDITIONAL_SDKS build setting, or directly as normal. The convention 
seems to be to install this into ~/Library/SDKs/Qt/$(PLATFORM_NAME).sdk, 
eg ~/Library/SDKs/Qt/macosx.sdk.
