Additional Include Directories aren't working

In Visual Studio C++, I add my project’s cocos2d folder into the additional include directories, though, I still include any of the files within that folder unless manually go to the cocos2d folder with the include thing.

I know that this might not be a problem with cocos2d itself, but I typed “…/cocos2d” into the additional include directories and I feel like I’m doing it wrong and that someone with knowledge of cocos2d may be able to help me set the correct directory or something
