eclipse - 异常 "cannot find dependent library"使用 javacv

Question

我尝试使用 JavaCV 在 eclipse 中实现一个程序。这是示例代码，

import static com.googlecode.javacv.cpp.opencv_core.*;
import static com.googlecode.javacv.cpp.opencv_imgproc.*;
import static com.googlecode.javacv.cpp.opencv_highgui.*;
public class JavaCVProj01 
         {

    /**
     * @param args
     */
    public static void main(String[] args) {
        // TODO Auto-generated method stub
        IplImage img = cvLoadImage("Paris.jpeg");
        cvShowImage("Paris",img);
        cvSmooth(img,img,CV_GAUSSIAN,13);
        cvShowImage("BlurImage",img);

        cvWaitKey();
        cvReleaseImage(img);

    }

}

当我运行程序时出现异常

我也为环境变量提供了正确的路径。我还从 javacv-bin 添加了外部 Jar 文件。我给的路径是类路径D:\opencv\build\x86\vc10\libD:\opencv\build\common\tbb\ia32\vc10D:\opencv\build\x86\vc10\staticlib

路径D:\opencv\build\common\tbb\ia32\vc10D:\opencv\build\x86\vc10\bin

我该怎么办？我还需要添加哪些依赖库？

只需将 opencv 目录复制到 C:\驱动器即可解决此问题。与正确设置所有路径相比，这可能是最简单的出路。 JavaCV 文档中某处提到了这一点(现在找不到)。
