[CMake] VS2010 tries to compile a file with *.res extension when its copied

[Aaron_Wright at selinc.com]

This is with both 2.8.3 and 2.8.4-rc1.

On a side note, VS2010 is not trying to compile the *.res file as part of 
the executable, because it is marked HEADER_FILE_ONLY, and in addition I 
can remove it entirely from the project. Instead, even when the *.res file 
appears no where in the solution explorer in VS2010 (except as a 
*.res.rule file), VS2010 is still trying to compile it. If I remove the 
*.res.rule file it stops trying to compile it. So basically its just 
something to do with the ADD_CUSTOM_COMMAND that copies the file.
