This seems really, really strange.  Have to reinstall Windows?  What about
just using another build directory?  It sure *seems* like there's some
problem in your CMakeFiles.txt where the way the filepath is being
constructed is incorrect.  But I don't think you've really provided enough
information to determine the problem.  Where does the name of the object
file come from?
