You only install the LIBRARY but not the ARCHIVE (the static import lib 
automatically created when you export functions from a lib on windows). 
A static library is also treated as ARCHIVE by cmake on windows.
So either remove LIBRARY or add a destination for ARCHIVE.
Another thing which comes to my mind is that a library is treated as 
RUNTIME - but I'm unsure atm :)

So best is - remove 'LIBRARY' and you'll be fine.
