You can't, at least until your require CMake 2.8.7 and get your changes
to FindQt4.cmake upstream ASAP.

Thats because CMake's FindQt4 (or rather Qt4Macros.cmake) has no support
for reading any kind of extra arguments for the dbusxml2cpp call from
source properties. Apparently your team added that to your FindQt4.cmake
file without pushing this change upstream, so your stuck with your
FindQt4.cmake version until the upstream one gained the same feature and
you can require that new cmake version that has this feature included.
