It is used for copy if different.  Every time you run cmake it always creates a .vcproj.cmake file.
Only if that files is different than .vcproj does cmake write the .vcproj file.   The vcproj.cmake
files are also used as files to depend on, that can tell vs when to re-run cmake.  
If you always re-wrote the .vcproj files it would cause a bunch of un-needed re-loads in
vs.
