CMake Windows: install *.dll in the correct location

[tdegeus]

The *.dll on Windows is currently being installed in %PREFIX%\Library\lib which should however be %PREFIX%\Library\bin. The fix is to set

install(TARGETS ...
           LIBRARY DESTINATION "lib"
           ARCHIVE DESTINATION "lib"
           RUNTIME DESTINATION "bin"
           ....)

Will open a PR.
