Ajouter un réseau au projet Qt

Question

J'essaie d'utiliser la bibliothèque QtNetwork et j'ai ajouté toutes les dépendances dans le fichier .pro. Mais quand je compile mon code Qt Creator échoue dans la construction du projet et affirme

C1083: Inclure "QTcpSocket": Aucun fichier ou répertoire - telnet.h: 4

Je pensais que l'ajout de réseau le fichier .pro serait suffisant?

networkmonitor.pro

TARGET = networkmonitor 
TEMPLATE = app 

# The following define makes your compiler emit warnings if you use 
# any feature of Qt which as been marked as deprecated (the exact warnings 
# depend on your compiler). Please consult the documentation of the 
# deprecated API in order to know how to port your code away from it. 
DEFINES += QT_DEPRECATED_WARNINGS 

# You can also make your code fail to compile if you use deprecated APIs. 
# In order to do so, uncomment the following line. 
# You can also select to disable deprecated APIs only up to a certain version of Qt. 
#DEFINES += QT_DISABLE_DEPRECATED_BEFORE=0x060000 # disables all the APIs deprecated before Qt 6.0.0

private:

Normalement, cela signifie que vous avez juste oublié de relancer qmake
