如果 Visual Studio 2012 / 2013 中的项目/解决方案中缺少文件，则报告错误/警告

视觉工作室不再支持宏，因此以下问题中的答案仅对以前的版本有效：

如果 Visual Studio 中的项目/解决方案中缺少文件，则报告错误/警告

当您构建缺少文件的解决方案时，Visual Studio 2012 / 2013 是否可以报告错误/警告？

我修改了谢尔盖的脚本以递归地处理文件夹。

更新：为每个项目添加了一个消息框弹出窗口，其中列出了 Thomas Svensen 在评论中建议的缺失文件

更新 2：现在将丢失的文件写入输出窗口并作为错误列表中的错误。这不会导致构建失败，只会导致错误列表中的一行。
