Migrating to Qt5: problem with QMAKE_UIC

[Predelnik]

Well I wanted to migrate project which uses custom(non-Qt) localization system to Qt5, so basically there was just simple line in .pro file:
@QMAKE_UIC += -tr UIC_GET_TEXT@

When I've tried to build it with Qt5, variable QMAKE_UIC didn't seem to affect anything. When I've found following lines in file changes-5.0.0:
@The QMAKE_INCDIR_QT, QMAKE_LIBDIR_QT, QMAKE_MOC, QMAKE_UIC, QMAKE_IDC, TEMPLATE & QT variables should not be defined any more. Furthermore, QMAKE_LIBS_X11SM is obsolete.@
But actually through some tries of googling this issue I can't seem to find the alternative solution how to apply "-tr" to each uic call. So my question is - is there anyway to do it?

Ok looks like, I've found that the possible way to do it is
@load (uic)
uic.commands += -tr UIC_GET_TEXT@
