qmake ignores network?

This is my *.pro file

TEMPLATE = app
TARGET =
DEPENDPATH += .
INCLUDEPATH += .
Qt += network
# Input
HEADERS += mainwindow.h shogiclient.h shogicmd.h shogierror.h
FORMS += mainwindow.ui
SOURCES += main.cpp mainwindow.cpp shogiclient.cpp shogicmd.cpp

but the resulting makefile contains no includes or anything for the network stuff. What is wrong here?

I'm so stupid.
It should be

QT += network

The variable is "QT" not "Qt":

Code:

---

QT += network gui xml # ... and so on, whatever you may need

---
