Works fine on my Arch.

Sorry, it does not work for me without the patch; I just tried it again:

video_filter/opencv_wrapper.c:42:20: fatal error: cxcore.h: No such file or directory
#include <cxcore.h>
^
compilation terminated.

Exporting the variables is not enough.
After reapplying the patch the compilation finishes.
