# 3 clion 配置qt编译器 #

# 4.1 在主项目中加载qt库 #

## 4.1.2 导入方法一 ##

** 1. 在这个CMakeLists.txt文件中配置:**

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzE1MjA0MTc5_size_16_color_FFFFFF_t_70 7][]

** 2.主程序**

#include <iostream>
    #include <QtWidgets/qwidget.h>
    #include <QtWidgets/qapplication.h>
    
    int main(int argc, char **argv) {
    
        QApplication app(argc,argv);
        QWidget qw;
        qw.show();
        app.exec();
        return 0;
    }

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzE1MjA0MTc5_size_16_color_FFFFFF_t_70 8][]

### 4.1.3 导入方法二  ###

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzE1MjA0MTc5_size_16_color_FFFFFF_t_70 9][]

**在这个主CMakeLists.txt文件中配置:**

这里使用的倒库方法与上面有区别这边直接用find\_package(), 不需要导头文件;

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzE1MjA0MTc5_size_16_color_FFFFFF_t_70 10][]

**在子模块CMakeLists.txt文件中配置:**

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzE1MjA0MTc5_size_16_color_FFFFFF_t_70 11][]

**3.子模块中使用**

#include <iostream>
    #include <qapplication>
    #include <qwidget>
    #include <QIcon>
    int main(int argc, char **argv) {
    
        QApplication app(argc, argv);
        QWidget qw;
        qw.setWindowTitle("我的第一个窗口");
        QIcon qi("../../01_helloworld/icon.png");
        qw.setWindowIcon(qi);
        //qw.setFixedSize(200,200);//设置初始窗口大小, 窗口不可放大放小
        //qw.setMaximumSize(600,600);
        //qw.setMinimumSize(10,50);
        qw.resize(500,800);//设置初始窗口大小, 窗口可放大放小
        qw.show();
        app.exec();
    
        return 0;
    }

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzE1MjA0MTc5_size_16_color_FFFFFF_t_70 12][]

**ubuntu18.04:**

1.安装c++编译环境

sudo apt install build-essential  //使用该命令会安装gcc,g++,make

2.安装缺失的库:

sudo apt install mesa-common-dev

安装多窗口控制台:

sudo apt install terminator  //不需要可以不装

3. 导入qt库与windos操作一致;

**草稿笔记: **

**方法一:**

cmake_minimum_required(VERSION 3.15)
    project(day13_09)
    
    set(CMAKE_CXX_STANDARD 14)
    
    set(CMAKE_AUTOMOC ON)  # 针对信号和槽 帮助我们处理，含有信号和槽的源文件,建项目时先加上
    set(CMAKE_AUTORCC ON)  # 针对图片的打包,建项目时先加上
    set(CMAKE_AUTOUIC ON)  # 针对UI文件,建项目时先加上
    
    # 1. 关联头
    include_directories(C:\\itheima\\stu\\include)
    include_directories(C:\\itheima\\teacher\\include)
    
    # 2. 查找库
    # find_package 回去查找是三个文件中的某一个
    # Findaa.cmake  | aaConfig.cmake  |aa-config.cmake
    #find_package(aa)
    
    # 设置模块的路径，好方便find_package 去查找这个库。一般在这个路径下会有一个文件 Finditheima.cmake  |  itheimaConfig.cmake
    set(CMAKE_MODULE_PATH C:/itheima)
    # 查找itheima库
    find_package(itheima)
    
    add_executable(day13_09 main.cpp)
    # 2. 关联库
    target_link_libraries(day13_09 ${heima_lib})

**方法二:**

set(CMAKE_AUTOMOC ON)  # 针对信号和槽 帮助我们处理，含有信号和槽的源文件,建项目时先加上
    set(CMAKE_AUTORCC ON)  # 针对图片的打包,建项目时先加上
    set(CMAKE_AUTOUIC ON)  # 针对UI文件,建项目时先加上
    
    
    set(CMAKE_PREFIX_PATH C:/env/qt/5.14.0/mingw73_64/lib/cmake)
    find_package(Qt5 COMPONENTS Widgets)
    
    add_executable(day02 main.cpp)
    
    # target_link_libraries(day02  ${Qt5Widgets_LIBRARIES}) #可以使用这种,qt内部变量
    target_link_libraries(day02 Qt5::Widgets)

**解锁apt:**

执行以下命令:

sudo rm /var/lib/apt/lists/lock /var/cache/apt/archives/lock /var/lib/dpkg/lock\*

sudo kill apt apt-get
