I get the following when I do a Cmake http://pastebin.com/QTP9qqC1

It is missing
1) sys/videoio.h - For the life of me I can't seem to find this file.

2) ffmpeg/avformat.h - It is present at /home/ubuntu/ffmpeg_build/include/libavformat/avformat.h but for some reason OpenCV wont look there.

a) Should I update the CMakeLists.txt of OpenCV to include the ffmpeg build path ? Worried it will messup my openCV install as it already detects ffmpeg and forcing a build path include might cause that to break.

b) please suggest the right way to do it.

To solve your problems, start by installing possible dependencies of OpenCV. This can be done by the following command:

sudo apt-get install libtbb-dev libeigen2-dev libqt4-dev libqt4-opengl-dev libopencv-dev build-essential checkinstall cmake pkg-config yasm libtiff4-dev libjpeg-dev libjasper-dev libavcodec-dev libavformat-dev libswscale-dev libdc1394-22-dev libxine-dev libgstreamer0.10-dev libgstreamer-plugins-base0.10-dev libv4l-dev python-dev python-numpy libtbb-dev libqt4-dev libgtk2.0-dev

When doing so, I have been successfully compuling 3.0 for the last year now.

OpenCV3.0 builds okay it is just that I get those missing files in the CMake list even after installing the packages above.

Please reopen a new issue with your complete CMAKE config output and build process. No reason in hijacking over 1 year old topics...
