MEX error: SDK 8 is not working

Hi all,

I have about 7 - 8 files that I'm trying to execute in Matlab by using the MEX makefile command. But I can't seem to overcome this SDK 8 error that is popping up. I'm using MatlabR2013a, and already installed both the 7.1 SDK and the 8 SDK. Matlab still isn't recognizing that the 8 SDK compiler exists though. Why is this? And does anyone have any solution as to how to fix this? My execution commands are written below if you want to know what the exact error message I'm getting is.

Been waiting for a response for a few days now. Guess contributors were taking off for Thanksgiving holidays.

Any help would be greatly appreciated though.

Thanks!
