Issue with UnsatisfiedLinkError in OpenCV Java Binding on macOS

Hi,

I am working on a Java project using OpenCV to capture and process video streams. Below is the code I am using in my main method:

public static void main(String gg[]) {
    try {
        Loader.load(org.bytedeco.opencv.opencv_java.class);
        System.loadLibrary(Core.NATIVE_LIBRARY_NAME);
        String streamUrl = "https://thisis urlvideo_h1.m3u8";
        VideoCapture cap = new VideoCapture(streamUrl);
        if (!cap.isOpened()) {
            return;
        }
        Mat frame = new Mat();
        while (cap.read(frame)) {
            if (frame.empty()) {
                break;
            }
            // Process and annotate the frame
            System.out.println("====================================");
            System.out.println(frame);
            System.out.println("+++++++++++++++++++++++++++++++++++++");
        }
        cap.release();
    } catch (Exception e) {
        e.printStackTrace();
    }
}

For dependencies, I am using the following Maven dependency:

<dependency>
    <groupId>org.bytedeco</groupId>
    <artifactId>opencv-platform</artifactId>
    <version>4.9.0-1.5.10</version>
</dependency>

Additionally, I installed OpenCV from the source with the following CMake flag:
-DBUILD_opencv_java=ON

However, when I run the code on my macOS machine, I encounter the following error:

java.lang.UnsatisfiedLinkError: 'long org.opencv.videoio.VideoCapture.VideoCapture_0()'

Could you please assist with resolving this UnsatisfiedLinkError issue? Is there anything specific to macOS I need to configure, or any steps I might have missed?

Thanks in advance!
