用VS2015编译Qt5.6.0，WebEngine支持XP

准备工作

1、下载icu库、openssl库

2、安装activePerl、python、git（请将git的bin目录加入path环境变量）

3、修改控制面板->区域->管理->更改系统区域设置->英语（美国）

4、退出360、保持连接网络

5、win10/win8操作系统，vs2015 update3补丁安装

6、下载qt5.6.0源码并解压：

a、修改文件\qtwebengine\src\3rdparty\chromium\third_party\skia\src\core\SkEdge.cpp，找到第231行的fCurveCount = SkToS8(1 << shift);修改为fCurveCount =
SkToS8(1i64 << shift);

b、修改\qtwebengine\src\3rdparty\chromium\third_party\ffmpeg\libavformat\wavdec.c，找到第554行修改为

        #if CONFIG_W64_DEMUXER

        if (CONFIG_W64_DEMUXER && wav->w64)

            left = find_guid(s->pb, ff_w64_guid_data) - 24;

        else

        #endif

这个是防止出现ffmeg报 error LNK2001: unresolved external  ff_w64_guid_data 的错误

7、如果你是win10请将C:\Program Files (x86)\Windows Kits\8.1\Lib目录下winv6.3拷贝一份并更名为win8，好像qt5.6.0是基于win8搞的。当然如果你能修改qt源码对应的目录也可以；这个主要是防止报FOLDERID_ApplicationShortcuts未定义的错误。

8、在任一目录建立批处理文件 build5.6.bat，填入以下内容（将等号后面的路径替换成你对应的路径）: 
set MSVC_PATH=C:\Program Files (x86)\Microsoft Visual Studio 14.0
set QMAKESPEC=win32-msvc2015
