VS2012添加全局包含目录

参考：http://www.curlybrace.com/words/2012/12/17/setting-global-c-include-paths-in-visual-studio-2012-and-2011-and-2010/

如果通过界面配置无效（重启VS后丢失），可以尝试直接修改文件：%LOCALAPPDATA%\Microsoft\MSBuild\v4.0\Microsoft.Cpp.Win32.user.props

修改文件时，把属性框里面的内容逐项拷贝到xml中去。

比如：

<?xml version="1.0" encoding="utf-8"?>
<Project DefaultTargets="Build" ToolsVersion="4.0" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
