error: ‘detectMarkers’ is not a member of ‘cv::aruco’ when compiling OpenCvSharpExtern

[ShuhuaGao]

Env: OpenCV 4.11 installed on ARM64, and I try to compile OpenCVSharp 4.11 from source.

Error:

It seems the API of the aruco module has changed since v4.7. Taking detectMarkers as an example, see the v4.6 API cv::aruco::detectMarkers and the v4.7 API afterwards void cv::aruco::ArucoDetector::detectMarkers.

I am wondering how to build OpenCvSharpExtern from source.
