编译udk源码

先编译UnrealBuildTool，再编译UDKGame Win32，会将各个项目中的文件打包到Unity_*EtAl.cpp类似的文件中，后续只要编译这些文件即可。

在Development\Src\UnrealBuildTool\System\LocalExecutor.cs:141中添加：

Console.WriteLine("Executing: {0} {1}", ActionStartInfo.FileName, ActionStartInfo.Arguments);

再生成UDKGame Win32项目，将输出窗口中的调试信息如：

复制黏贴到vs2010命令行中，手动生成。

最后有一个link命令能生成UDKGame.exe
