我正在尝试构建自定义的ffmpeg版本4.1。众所周知，ffmpeg4.1需要libavcodec.so.58和其他相关库（最新）。我的代码中有一些与opencv相关的功能，例如cvLoadImage等。我更新了libopencv-highgui-dev，libopencv_core-dev和libopencv_imgproc-dev库。运行makefile时，出现以下错误，

我清楚地链接了最新的库，并将它们包含在我的makefile中。错误列表提示我，libopencv-highgui.so指向libavcodec.57版本的api。 opencv是否未升级为支持libavXX.so.58库？还是我在这里做错了。
请对此提供帮助，否则任何建议都会有所帮助。
