cmake 基本入门（编译可执行文件和动态库）

单文件

cmake_minimum_required(VERSION 3.4.2)

project(single) # 定义项目名称

add_executable(single main.cc) # 添加可执行文件 

main.cc 如下

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

double power(double base, int exponent)
{
    int result = base;
    int i;

    if (exponent == 0) {
        return 1;
    }
    
    for(i = 1; i < exponent; ++i){
        result = result * base;
    }

    return result;
}

int main(int argc, char *argv[])
{
    if (argc < 3){
        printf("Usage: %s base exponent \n", argv[0]);
        return 1;
    }
    double base = atof(argv[1]);
    int exponent = atoi(argv[2]);
    double result = power(base, exponent);
    printf("%g ^ %d is %g\n", base, exponent, result);
    return 0;
}
