warning LNK4089: all references to "SHELL32.dll" discarded by /OPT:REF

警告： warning LNK4089: all references to "SHELL32.dll" discarded by /OPT:REF。

原因：The linker discarded all packaged functions that referenced exports in dynamic-link library. As a result, dynamic-link library and its import library are unneeded。

解决方法1：在Project-->Setting->Link选项中的Object/library modules中添加"/OPT:NOREF "。

解决方法2：使用"#pragma warning(disable:4089)"屏蔽该warning。
