一、简单文件的编译
有如下的目录结构:
 
 其中 helloworld.cpp如下:
#include <iostream>
using namespace std;
int main()
{
    printf("hello world my name is Ty!");
    return 0;
}
CMakeLists.txt如下:
cmake_minimum_required(VERSION 3.16.3)
project(HELLOWORLD)
add_executable(helloworld_cmake helloworld.cpp)
接下来新建一个build的文件夹
 ty@ty-virtual-machine:~/桌面/code/5.5$ mkdir build
 ty@ty-virtual-machine:~/桌面/code/5.5$ cd build
 ty@ty-virtual-machine:~/桌面/code/5.5/build$ cmake …
 …
 ty@ty-virtual-machine:~/桌面/code/5.5/build$ make
 
 运行结果:
 
二、多个文件夹的编译
有如下的目录
 
 swap.h:
#pragma once
#include <iostream>
class swap
{
public:
    swap(int a,int b)
    {
        m_a = a;
        m_b = b;
    }
    void run();
    void printInfo();
private:
    int m_a;
    int m_b;
};
swap.cpp:
#include "swap.h"
void swap::run()
{
    int ntemp;
    ntemp = m_a;
    m_a = m_b;
    m_b = ntemp;
}
void swap::printInfo()
{
    printf("m_a = %d,m_b = %d\n",m_a,m_b);
}
main.cpp:
#include "swap.h"
int main(int argc, char **argv)
{
    swap swapth(10, 20);
    swapth.printInfo();
    swapth.run();
    swapth.printInfo();
    return 0;
}
其中CMakeLists.txt内容如下:
make_minimum_required(VERSION 3.16.3)
project(SWAPPRO)
include_directories(include)
add_executable(mymain_cmake main.cpp src/swap.cpp)
然后创建build文件夹:
 mkdir build
 然后进入:cd build
 接着执行 cmake …
 最后执行 make
