[CMake] Details on MSVS Win64 LNK1112 static library link (archiver/librarian) issue

[Andreas Mohr]

Hi,

I've added a new note to
"0011240: VS 2010 Win64 does not correctly set /MACHINE:x64 in the solution project files"
  http://public.kitware.com/Bug/view.php?id=11240

(e.g. zlib Win64 is a prominent case of breakage here)

If some of the CMake platform setup wizards would happen to want to
have a look at this case... (some sizeable infrastructure extension
probably required)

Thanks,

Andreas Mohr
