Can not build on MacOS #26780
Description
System Information
OpenCV Version: 4.10.0
Platform: MacOS 14
Compiler: Xcode 15.4
Python Version: 3.11
Detailed description
When building OpenCV from source with the given setup the build will fail with the following error:

Highligh here is
error: field has incomplete type 'std::exception_ptr'
which appears due to a missing #include <exception>.
Steps to reproduce
Run the following commands to build OpenCV:
cmake .. -G "Ninja" -DCMAKE_C_COMPILER=cc -DCMAKE_CXX_COMPILER=c++ -DCMAKE_BUILD_TYPE="Release"
cmake --build .See also a build in Github Actions CI failing here: https://github.com/Malacath-92/Proxy-PDF-Maker/actions/runs/12786776491/job/35644533639
This build uses conan as a package manager, but it essentially executes the above commands during resolution of dependencies.
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)
