These errors are completely new to me.
mismatch detected for '_MSC_VER': value '1600' doesn't match value '1700'
This apparently means that you are using a library that was compiled for VS2010 in a VS2012 project.
You can't use a library that was compiled with a different compiler, and libraries from different VC++ versions aren't compatible.
For now I assume that the other errors might be caused by this, so you should first fix this.
SFML is the release candidate that doesnt require any building.
What do you mean release candidate? If you just downloaded sfml then you have 2.0, or if you dowloaded from github then you have a newer version but then you would have to build it yourself. If you are really talking about the SFML2-RC from last year, then I must say that tgui isn't compatible with that version (but you don't seem to get errors when building tgui so that can't be the case).
