I am building mu customised ffmpeg4.1 version. I am using cvLoadImage and some other opencv functions in my code, so I linked highgui-dev library as -lopencv_highgui in my Makefile. As we know that ffmpeg4.1 needs libavcodec.so.58 and other related libraries(newest). I updated the libopencv-highgui-dev, libopencv_core-dev and libopencv_imgproc-dev libraries. When I run the makefile I got the following errors

I have clearly linked the newest libraries and included them in my makefile. Errors list suggesting me that, libopencv-highgui.so is pointing to libavcodec.57 version api's. Has opencv not upgraded to support libavXX.so.58 libs? or am I doing anything wrong here.

Can we link this libopencv_highgui library to point to libavXX.so.58(newer libs)? or should I need to compile and build the binaries of libopencv_highgui with libav newer libraries? Is it possible?

Please help me with this, or any suggestions would be helpful.
