I have installed OpenCV using the instructions in https://help.ubuntu.com/community/OpenCV
$ sudo su
$ sudo apt-get install build-essential
$ sudo apt-get install libavformat-dev
$ sudo apt-get install ffmpeg
$ sudo apt-get install libcv2.3 libcvaux2.3 libhighgui2.3 python-opencv opencv-doc libcv-dev libcvaux-dev libhighgui-dev
now when i execute "pkg-config --cflags --libs opencv" i get this error:
Package opencv was not found in the pkg-config search path.
Perhaps you should add the directory containing `opencv.pc'
to the PKG_CONFIG_PATH environment variable
No package 'opencv' found
how can I resolve this problem?
-------UPDATE-------
OK, I figured out how to solve the problem...
I made a file named "opencv.pc" and copied it to "/usr/local/lib/pkgconfig" Then i added these two lines to ".bashrc":
PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/local/lib/pkgconfig
export PKG_CONFIG_PATH
that's it! everything is OK now.
the contents of the file are:
prefix=/usr
exec_prefix=${prefix}
includedir=${prefix}/include
libdir=${exec_prefix}/lib
Name: opencv
Description: The opencv library
Version: 2.x.x
Cflags: -I${includedir}/opencv -I${includedir}/opencv2

UPDATE - 2014
it seems that the ubuntu community has completed the documentation on installing openCV, all you have to do now is to download the installation script from https://github.com/jayrambhia/Install-OpenCV/blob/master/Ubuntu/opencv_latest.sh and execute it.

don't forget to make it executable:
chmod +x opencv_latest.sh
then
./opencv_latest.sh
