cmake入门1之hello world

环境

ubuntu18

cmake version 3.17.3

准备文件

新建一个文件夹demo1，新建两个文件：CMakeLists.txt、helloworld.c

parallels@Lincoln:~/workspace/cmakedemo/demo1$ pwd
/home/parallels/workspace/cmakedemo/demo1
parallels@Lincoln:~/workspace/cmakedemo/demo1$ tree
.
├── CMakeLists.txt
└── helloworld.c

helloworld.c文件源码如下：

#include <stdio.h>

int main() {
    printf("hello world\n");
    return 0;
}

CMakeLists.txt：cmake的配置文件

#设置cmake的最小版本要求
cmake_minimum_required(VERSION 3.10)
#设置工程名字为 ylk_hello
project(ylk_hello)
#使用helloworld.c生成可执行程序hello
add_executable(hello helloworld.c)

使用cmake

1、生成配置

parallels@Lincoln:~/workspace/cmakedemo/demo1$ cmake .
