Error in Release mode but not in Build mode

I recently made a project using opencv and c++ in visual 2008 When i build the project in Debug mode - i don't face any issues - but when i build it in release mode i get the following errors:

1>test.obj : error LNK2001: unresolved external symbol _cvHaarDetectObjects
1>test.obj : error LNK2001: unresolved external symbol _cvCvtColor

Check Linker->Input->Additional Dependencies settings in the Release configuration ; you have undoubtedly forgotten to include the OpenCV libraries. Just copy-paste them from the Debug configuration, but don't forget to remove the d suffix.

E.g. cv210.lib : Release mode and cv210d.lib : Debug mode.

You are not including the same libraries in your release build that you include in your debug build. "unresolved external symbol" means it cannot find the implementation for a function you are referencing.

This happens when you give Additional Dependencies to Debug mode but not in Release.
