FreeBSDでOpenCVを用いたサンプルをコンパイルしたいのですが、パッケージが存在しないとエラーが出てしまいます。FreeBSD上でOpenCVをインストールした結果は以下のとおりです。

    ===>   NOTICE:
    
    The opencv port currently does not have a maintainer. As a result, it is
    more likely to have unresolved issues, not be up-to-date, or even be removed in
    the future. To volunteer to maintain this port, please create an issue at:
    
    https://bugs.freebsd.org/bugzilla

ソースコード

```

    import org.opencv.core.Core;

    import org.opencv.imgcodecs.Imgcodecs;
    import org.opencv.imgproc.Imgproc;

      public static void main(String[] args) {
        //System.loadLibrary(Core.NATIVE_LIBRARY_NAME);
    
        String input = "/home/○○/lena.jpg";
        String output = "/home/○○/opencvsample/result.jpg";
        //Mat matrixSrc = new Mat();
        //Mat matrixDst = new Mat();
    
        // 入力画像の読み込み
        //matrixSrc = Imgcodecs.imread(input);
        // カラー画像をグレー画像に変換
        //Imgproc.cvtColor(matrixSrc, matrixDst, Imgproc.COLOR_BGR2GRAY);
        //Imgcodecs.imwrite(output, matrixDst);

どうすればOpenCVを用いたソースがコンパイルできるか分かる人回答お願いします。
