I know that cmake 2.10 (2.12?) started to enforce no white spaces..so, that can lead to alot of error messages in cmake itself, regarding paths.
I could only find one relevant link to this (search: 1600 1800)
I ran across this problem one time myself..but, my solution was just to change the target compiler to the correct one (had just updated to vs2013.)
There was at least one other case I recall as well and I think it was compiler-related, also.
This link indicates another scenario:

But, I wouldn't recommend the fix unless you are 100% sure it applies to you.
