OpenCV 2.4.4a - OSX 10.8.3 CMake + GPU + FFMPEG (Bug #2939)

Hello,

There's a build error when using CMake on OSX 10.8.3, with GPU and FFMPEG, during the compilation of OpenCV 2.4.4a

Here is the error message during 'make'.

Linking CXX shared library ../../lib/libopencv_gpu.dylib
ld: library not found for -lavcodec
collect2: ld returned 1 exit status
make[2]: *** [lib/libopencv_gpu.2.4.4.dylib] Error 1
make[1]: *** [modules/gpu/CMakeFiles/opencv_gpu.dir/all] Error 2
make: *** [all] Error 2

Below is the CMake Configuration.

Any suggestions on what I may have done wrong?
