You need to add path to "opencv2/<module>" directory to your .pro file, for each module listed in above error. Modules should be in "C:/OpenCV2.2/modules".
For example, "core" module is in:

C:\OpenCV2.2\modules\core

, it has "include" subdir, which contains the path referenced in cv.h above. So for this module, entry in .pro file would be:

INCLUDEPATH += C:/OpenCV2.2/modules/core/include

Look into your OpenCV 2.2 installation directory and add all missing modules path to your .pro file.

hey when i download opencv 2.2 from sourcefroge i have two option
1)opencv.zip
2)opencv.exe for vs2010

which one to download so that i can use it with Qt creator.....

[mind_freak]

i don't know which to select so that i can configure it properly with Qt Creator 2.0.95,

Which compiler are you using ? I think there are prebuilt packages available for Visual C++ compilers, so this ".exe for vs" is probably this package.
I'm using g++, so I've had to build OpenCV myself ( not really difficult, just download CMake and click few times, I think there is even a step-by-step tutorial somewhere ).
So it depends on the compiler, if you use g++ download something like "OpenCV-2.2.0-win.zip".

m using Nokia Qt sdk ,so which compiler does it consist of ??

[squidge]

MinGW/GCC, unless you specified otherwise.

I need to know how to fix the following problem that I get when I try to configure the CMake. please I need some help.
