cef-3.2623 build on vs2013

1. 参文“在Windows下编译Cef3.2623并加入mp3、mp4支持（附带源码包和最终DLL）”下载包
http://blog.csdn.net/zhuhongshu/article/details/54193842

2. 创建build.bat
e:\cef\
source
automate-git.py
build.bat

如下：

set CEF_USE_GN=0
set DEPOT_TOOLS_WIN_TOOLCHAIN=0
set GYP_DEFINES=component=shared_library
set GYP_GENERATORS=msvs-ninja,ninja
set GYP_MSVS_VERSION=2013
set GYP_MSVS_OVERRIDE_PATH=c:\Program Files (x86)\Microsoft Visual Studio 12.0

python automate-git.py --download-dir=e:\cef\source --branch=2623 --no-update --no-debug-build --build-log-file --verbose-build --force-distrib --force-build

3. 构建
cd e:\cef
./build.bat

4. 报错
