Subject: [PATCH] Add new cmake configure option DBUS_USE_WINE

If this variable is set, ctest uses wine to run cross compiled
test applications. Otherwise, they are assumed to run on a native
Windows operating system.

The new cmake variables Z_DRIVE_IF_WINE and TEST_WRAPPER have been
added to support this function.
