I'm not in position to test DWin, but did you run dsss install at any point?
Does DWin support it? When that is done, dsss will know without any further
ado how to find it when compiling your application.

Otherwise it is as with dmd, add -Ipathtodwinimports to your commandline,
and similar for libraries and library paths. The actual arguments are
processed in rebuild, so the helptext there should be of some help.
