Description
Trying to build opencv-2.4.4a with ffmpeg.
First question is what flag to pass cmake to just turn off building HIGHGUI.
Second question is how to have cmake correctly discover ffmpeg include files.
Looking at the attached log I see the correct ffmpeg library has been discovered.
And cmake is unable to find the libavformat.h file even though pkg-config --cflags
is returning the correct include file path.
There are numerous tickets about this, none of which correctly explain how to fix this.
Let me know the correct cmake incantation to locate the ffmpeg header files.
Thanks.

Cmake files are greek to me and it appear via cmake --trace that the
libavformat.h checks may only be for Gentoo Linux.
If this is the case, probably best to change the output text for the test
and failure to specifically say these are only for Gentoo.
And I could be wrong about this.

Does look like this check is only for Gentoo Linux.
Please update message to clarify the check is only for Gentoo.
If this assumption is incorrect, then please update this ticket with the correct
way to discover (-D... definition) where these files live.
Thanks.
