Deploying with Rsync does not work on Windows

QtCreator gives the following error if I try to deploy to linux device from windows using Rsync from cygwin or mingw:

The source and destination cannot both be remote.

The reason seems to be in local path, where rsync considers any directory with a colon to be remote. Fix would be to use cygwin or unix style representations: "/cygdrive/c/dir" or "/c/dir".

There doesn't seem to exist a native rsync for windows, as rsync uses posix functions.
