Vuforia SDK for iOS and Mountain Lion

If you downloaded the Vuforia SDK from https://ar.qualcomm.at/sdk/ios and you're running Mac OS X Mountain Lion, make sure that you disable Gatekeeper before running the installer.

To disable Gatekeeper, open "System Preferences"
                                       select "Security & Privacy"
                                       click on the little lock in the lower left corner to allow setting changes (you need to be a admin user and you need your login password)
                                       select "Allow applications downloaded from: Anywhere"
