UE4 服务端构建后启动错误的解决方法

构建独立服务端后启动报错：

[2016.04.15-11.22.50:980][  0]LogMaterial:Error: The global shader cache file 'F:/EpicGames/UnrealEngine-4.11.0-release/Engine/GlobalShaderCache-PCD3D_SM5.bin' is missing.

Your application is built to load COOKED content. No COOKED content was found; This usually means you did not cook content for this build.

It also may indicate missing cooked data for a shader platform(e.g., OpenGL under Windows): Make sure your platform's packaging settings include this Targeted RHI.

Alternatively build and run the UNCOOKED version instead.

原因：没有先构建client模式，也就是没有执行官方wiki步骤上的第5步

https://wiki.unrealengine.com/Dedicated_Server_Guide_(Windows_%26_Linux)#5._Create_.3CMyGame.3EServer.Target.cs

构建完client之后，再添加文档上面提到的Server.Target.cs配置文件，然后重新生成VS工程文件（Generate Visual Studio project file），然后再选择需要的Server模式（development或者shipping等）构建server，然后再启动。
