Just to clarify: you need to distinguish between "(Minimum) BUILD  SDK" and "Minimum DEPLOYMENT Target".

See here: http://lists.qt-project.org/pipermail/interest/2014-October/013718.html

QMAKE_MAC_SDK and QMAKE_MACOSX_DEPLOYMENT_TARGET is what you're after.

Usually you want to build against the latest SDK (e.g. "macosx10.11"). Setting the Deployment Target to a lower value (e.g. "10.8") will "weak-link" any symbols which were not available on that target. Off course if you want to use features of a later SDK you need to dynamically check for their existence.

(I am not an Xcode/Cocoa/ObjC expert, so not 100% sure about the "weak-linking part" - but as long as you don't use Cocoa directly, but Qt exclusively, you don't need to bother anyway: Qt does it all for you, down to the lowest supported OS X).

Not sure about C++11 support (in case that's the problem here anyway), but according to 

  http://blog.michael.kuron-germany.de/2013/02/using-c11-on-mac-os-x-10-8/

it should be supported since OS X 10.7.
