一、最简单的cmake实现demo0

1. 添加源文件main.cpp

#include<stdio.h>
#include<stdlib.h>
#include<math.h>

int main(int argc, char* argv[]) {
    if (argc < 2) {
        printf("please input %s number: \n", argv[0]);
        return 1;
    }   
        
    double input = atof(argv[1]);
    double out = sqrt(input);
        
    printf("%f sqrt is %f\n", input, out); 
    return 0;
}

2. 编写CMakeLists.txt

# cmake 最低版本要求
cmake_minimum_required (VERSION 2.8)
# 项目名称
project (Main)
# 指定生成目标
add_executable(main main/main.cpp)

3. 新建build目录文件，执行cmake .. && make

4. 运行./main 10
