Requring all lib in lib (debug+release) and all dll in bin without 
copying can be done with a hack that is not "the usual CMake way"...
I can ask the CMake mailing list, but it seems a non common usage: it 
seems to me the default is to keep .lib and .dll in the same place with 
the same prefix.
By using .. in the prefix, one can force placing stuff... but is 
probably not thorougly tested (as debug / release inconsistency shows)
I have posted a question on CMake linst

Even to me this seems the most straigthforward route, but, if you do not 
want to rename stuff, you need copying.
The copying can be limited to only the clashing examples though
