In my error list, VS2013 says I'm missing includes opus.h and jpgd.h in VoiceCodecOpus.cpp and JpegImageWrapper.cpp, any ideas?

Hi

During my Unreal 4.0 source build the application says I am missing opus.h and jpgd.h from VoiceCodecOpus.cpp and

JpegImageWrapper.cpp respectively. I decided to download the trial version of VS2103 professional and install the DX runtime in order to build Unreal from source in order to give it a try. Well, failure.

Any Suggestions? Am I missing libraries or configure VS2013 to point to a directory to search for the files because they are not located in source?

Thanks,

Johngo
