Detailed description

I'm using platforms/ios/build_framework.py to build opencv for ios swift project.
When I run the script(build_framework.py) without any arguments, it works well.
But if I put arguments --without, the build fails.

I checked this issue in Xcode 11.5, 11.7, 12.0 and all the same result.
The error says

CMake Error at modules/objc/generator/CMakeLists.txt:86 (add_dependencies):
Cannot add target-level dependencies to non-existent target "opencv_world".

This line of code makes change if I use argument --without.

Steps to reproduce

python platforms/ios/build_framework.py build_ios_without_doublecheck_2 --without calib3d
