-The script builds OpenCV.framework for iOS.
-The built framework is universal, it can be used to build app and run it on either iOS simulator or real device.
-
-Usage:
-    ./build_framework.py <outputdir>
-
-By cmake conventions (and especially if you work with OpenCV repository),
-the output dir should not be a subdirectory of OpenCV source tree.
-
-Script will create <outputdir>, if it's missing, and a few its subdirectories:
