qtcreater中工程文件的模块化管理（.pro文件和.pri文件的创建和管理）

.pro

1、创建一个.pro文件

例如：在home文件夹下创建一个home.pro，然后用qtcreater打开

 2、将level_1的工程文件目录转移到home文件目录下

 3、在home.pro添加如下语句

TEMPLATE = subdirs
SUBDIRS += level_1

工程管理界面变成如下所示

 

.pri

1、在level_1目录下添加level_2目录，并在level_2目录下创建level_2.pri文件

 2、在level_1.pro添加如下语句

include($$PWD/level_2/level_2.pri)           
INCLUDEPATH += $$PWD/level_2

 工程管理界面变成如下所示

 3、最后在pri文件里面添加各种库、资源文件和配置了

QT += core
QT += gui-private
# TODO: Define your C++ version. c++14, c++17, etc.
CONFIG += c++11
# The following define makes your compiler emit warnings if you use
# any feature of Qt which has 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
isEmpty(level_2_PARENTPATH) {
    message( 'level_2_PARENTPATH is empty. use default value.' )
    level_2_PARENTPATH = $$PWD/../
} else {
    message( 'level_2_PARENTPATH is not empty.' )
    message( $${level_2_PARENTPATH} )
}
INCLUDEPATH += $$PWD
INCLUDEPATH += $${level_2_PARENTPATH}
INCLUDEPATH += $${level_2_HEADERPATH}
HEADERS += \

SOURCES += \

win32-g++ {
    message("compiling for windows g++. mingw or msys or cygwin.")
    INCLUDEPATH += $${level_2_HEADERPATH}win32-gcc 
	CONFIG(debug, debug|release) {
	} else {
	}	
}
