预定义的宏列表中没有这样的东西- http://msdn.microsoft.com/zh-CN/library/b0084kay%28v=vs.100%29.aspx 。

There is no such thing in predefined macro list - http://msdn.microsoft.com/en-us/library/b0084kay%28v=vs.100%29.aspx .

但是，默认情况下，如果是静态库项目，MSVC会将 _LIB 添加到预处理器定义列表中。 >
（还会为DLL添加 _USRDLL ）

But by default MSVC adds _LIB to preprocessor definition list, if it's a "static library" project.
(also it adds _USRDLL for DLLs)

编辑：在Visual Studio 2017中，DLL的定义为 _WINDLL （来自IDE应用的 Windows动态链接库属性表）。 _LIB 定义不再可用。

In Visual Studio 2017 the definition for DLLs is _WINDLL (from the "Windows Dynamic Link Library" property sheet applied by the IDE). The _LIB definition is no longer available.

另一种解决方案是使用以下预处理器定义向项目添加属性表（签入版本控制存储库）： _ $（ OutputType）;％（PreprocessorDefinitions）。

An alternative solution is to add a property sheet to the project (checked into your version control repository) with the following preprocessor definition: _$(OutputType);%(PreprocessorDefinitions).

$（OutputType）将解析为DLL的 library和静态库的 staticlibrary，分别导致 _library 和 _staticlibrary 定义（或 _exe （对于应用程序）。

$(OutputType) will resolve as "library" for DLLs and "staticlibrary" for static libraries, resulting in _library and _staticlibrary definitions respectively (or _exe for applications).

％（PreprocessorDefinitions）将堆叠先前属性表中的定义。

%(PreprocessorDefinitions) will stack definitions from previous property sheets. Make sure it is included in the project properties as well!
