The entire AssetsLibrary framework is deprecated since iOS 8.0. The code
used in the camera example code can use UIKit to save videos to the
camera instead, which allows to avoid linking with PhotoKit instead to
prevent increasing the iOS deployment target.

- cmake dependencies search (WITH_MFX option)
- raw H264, H265, MPEG2 encoding and decoding
- tests for supported formats

Added bitcode flag to c flags

Fixed directories and targets with static

Bitcode parameter fixed

Fixed script for static library

Fixed parameters in build function

Updated cmake common toolchain

Added changes to OpenCV Utils

Updates to cmake

Fixed path in framework destination and added UIKit dependency

Dynamic plist for framework

Lib version removed hardcoded value

Removed trailing whitespace in toolchain

* Removed trailing whitespace

* Fixed typo in comment

* Renamed bitcode variable to bitcodedisabled

* Fixed target device family

Fixed ximea cmake settings for 32bit win build and linux.

Fix C++/CX support for all WINRT and bring back native-mode only support which was removed

the last kernel that allowed compiling this code was 2.6.37 which was
released almost 5 Years ago. So probably it does not get much testing
any more. Furthermore even back then one was better off using the V4L2
API.

The only change touching currently used code is the removal of the
global V4L2_SUPPORT variable.

- replaced m3api/m3apiX64 binaries with latest xiapi32/xiapi64 to
support latest camera models
- added new parameter definitions to videoio_c.h and
SetProperty/GetProperty calls
- added acquisition resetting for specific parmateters in SetProperty
call
- added new error return value evaluators
