Error MSB3075 When Building UE4

I downloaded Unreal Engine’s source code by following the instructions on GitHub, but I’m getting this error when I build the engine:

2>UnrealBuildTool : error : UBT ERROR: Failed to produce item: D:\UE4\UnrealEngine\Engine\Intermediate\Build\Win64\UE4Editor\Development\MovieSceneTools\UE4Editor-MovieSceneTools.lib
