Use CMake to link libraries and include directories. It makes your life easier and also for anyone else who will be extending/reading your code in the future.
For example, to link OpenCV, use the follow lines of code:
FIND_PACKAGE( OpenCV REQUIRED )
TARGET_LINK_LIBRARIES( myProject ${OpenCV_LIBS} )
Be sure to link the debug libraries and only the debug libraries. I once had this problem while mixing debug and non debug libraries in debug mode.
