I've followed your suggestion but unfortunately it doesn't work.

It appears that, if a project uses uic and moc-generated source files, the 
add_library() macro also needs the output of QT4_WRAP_CPP() and 
QT4_WRAP_UI().  So, it's more like the following:

add_library(ui STATIC ${ui_SOURCES} ${ui_HEADERS_MOC} ${ui_FORMS_HEADERS} )
