Generally, While linking, it looks for the symbols in the .lib files specified under the Link Settings; the .lib files must be available in the lib path.
Try to add the path to look for the lib files under Project Settings tab.
That's what I think I've done (Project Settings - Linker - General - Additional Library directories). I've also tried to add the .lib file with the full path, though it doesn't make a difference. Also, when I list a nonsense library in the dependencies, it complains, so I assume it can find the library I specified.
