Fatal error C1083 Cannot open include file

Hello I tried to compile the Unreal source and I received this error.
“C:\Users\user\Documents\UnrealEngine\Engine\Source\Runtime\Core\Private\Misc\Compression.cpp(13): fatal error C1083: Cannot open include file: ‘ThirdParty/zlib/zlib-1.2.5/Inc/zlib.h’: No such file or directory”

I have Visual Studio 2013 Ultimate. But I also have Visual Studio 2010 pro if that matters.

Any one have suggestions?

It sounds like you may not have downloaded and extracted the two zip archives containing additional dependencies mentioned in the README file (see also this page).

Hello Neverender,
So I had already downloaded and extracted the dependencies, though it seems I extracted to the wrong level of the folder structure. I moved them all and now the build succeeds, thank you for your help.
