CCSv5 new Qt project build error

Hi
on CCSv5 I try a new QT project:
menu file --> new --> Qt gui project
I set the name "qt_miaprova"
I don't add code
I select build project and I see the following error:

make debug
make -f Makefile.Debug
make[1]: Entering directory `/home/beta/workspace/qt_miaprova'
make[1]: qt_miaprova.ui: Command not found
make[1]: *** [ui_qt_miaprova.h] Error 127
qt_miaprova.ui -o ui_qt_miaprova.h
make[1]: Leaving directory `/home/beta/workspace/qt_miaprova'
make: *** [debug] Error 2

I also tried to import the project example "addressbook.pro"
and after the build projcet I have the same error.
Any suggest?
