added script to build the universal opencv2.framework for iOS device and simulator. fixed opencv_world cmake script to create static libopencv_world.a for iOS. temporarily disable compressed file storages in the case of iOS (to avoid dependency of zlib)

""" |
||||
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 SVN 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: |
||||
|
||||
<outputdir> |
||||
build/ |
||||
iPhoneOS/ |
||||
[cmake-generated build tree for an iOS device target] |
||||
iPhoneSimulator/ |
||||
[cmake-generated build tree for iOS simulator] |
||||
OpenCV.framework/ |
||||
[the framework content] |
||||
|
||||
The script should handle minor OpenCV updates efficiently |
||||
- it does not recompile the library from scratch each time. |
||||
However, OpenCV.framework directory is erased and recreated on each run. |
