Unable to build macOS Catalyst version of OpenCV framework (osx/build_frameworks.py) #23507
Description
System Information
OpenCV version: 4.7.0 (but I also tried 4.6.0)
Operating system: macOS 13.3.1 / Apple M2 Pro chip
Cmake version: 3.26 (but tried also other versions)
Detailed description
I am building XCFramework from openCV sources. When I try to build for simulator, device or macOS archs, everything works. However, when I want to include Mac Catalyst arc, the build fails.
I tried different openCV versions (4.6.0, 4.5.0) and CMake versions (3.26, 3.25, 3.24).
What I realised, that the problem is not in build_xcframework.py, but in build_xframework.py in in platforms/osx directory. So that can be isolated to this script.
Steps to reproduce
run build_framework from platforms/osx
python build_framework.py --catalyst_archs arm64 --framework_name opencv2 out --build_only_specified_archsI got error:
CMake Error at CMakeLists.txt:160 (message):
CMake fails to determine the bitness of the target platform.
Please check your CMake and compiler installation. If you are cross-compiling then ensure that your CMake toolchain file correctly sets the compiler details.
The complete log from build script:
Using MacOS ARCHS=None
Using Catalyst ARCHS=['arm64']

Issue submission checklist
- I report the issue, it's not a question
- I checked the problem with documentation, FAQ, open issues, forum.opencv.org, Stack Overflow, etc and have not found any solution
- I updated to the latest OpenCV version and the issue is still there
- There is reproducer code and related data files (videos, images, onnx, etc)
