*.pro (project)典型例子

TEMPLATE = app
CONFIG += QT
QT += core gui
# 生成目标名
TARGET = app

SOURCES += main.cpp/
        widget.cpp
HEADERS  += widget.h
FORMS    += widget.ui

*.pri (include)

SOURCES += main.cpp/
        widget.cpp
HEADERS  += widget.h
FORMS    += widget.ui

app.pro 可简化,对大点的项目

TEMPLATE = app
CONFIG += QT
QT += core gui

TARGET = propriprfprl
include(app.pri)

*.prf (feature)

CONFIG+=QT
win32:CONFIG += console

• load(app.prf) 等价 include(app.prf)

*.prl (link)
