Why won't my project build for Windows?

Rather foolishly, we’ve been working on a prototype game all week, but we haven’t been building (just testing in editor). When it came time to show it off, I tried to build the project and it failed. I’ve attached the full build log, but I suspect this is the interesting bit:

Our prototype is based on the TPP demo. I created a couple other template projects and built them just fine, so I’m not sure what the issue is. Any thoughts?
