概要

上一节中实现了对单个cpp文件用cmake编译。这一节升级一下

整体代码

main.cpp

#include <iostream>
#include "person.h"

using namespace std;

int main()
{
    person me = person("langdaoliu", 28, "engineer");
    me.printInfo();
    return 0;
}

person.cpp

#include "person.h"

person::person(){
    cout<<"new person"<<endl;
}
person::person (string name, int age, string work) {
    this->age = age;
    this->name = name;
    this->work = work;
}
void person::printInfo(){
    printf("name: %s age: %d work: %s\n",this->name.c_str(), this->age, this->work.c_str());
}

person.h

#pragma once
#include <iostream>
using namespace std;

class person{
    private:
        string name;
        int age;
        string work;
    public:
        person();
        person(string name, int age, string work);
        void printInfo();
};

CMakeLists.txt

cmake_minimum_required(VERSION 2.6) # cmake最低版本
project(demo1) #项目名称
set(CMAKE_CXX_STANDARD 11) #设置C++编译版本
set(CMAKE_BUILD_TYPE "Debug") # 默认是Release模式，设置为Debug才能调试

set(EXECUTABLE_OUTPUT_PATH ${PROJECT_SOURCE_DIR}/bin) #设置可执行文件生产的路径

aux_source_directory(. SRC_LISTS) #.下所有的cpp文件打包到变量SRC_LISTS中
add_executable(demo ${SRC_LISTS}) #生成可执行文件demo

运行结果
