Linux下使用cmake的简单示例

Posted 2020-12-02 guanghma

1. 编辑C程序文件，命名为main.c

#include <stdio.h>

int main(void) {
    printf("Hello World.
");
    return 0;
}

 

2. 编写CMakeLists.txt文件，保存在main.c同路径下

#Minimum required CMake Version
cmake_minimum_required(VERSION 3.6.1)

#Project Name
project(hello)

#把当前目录(.)下所有源代码文件和头文件加入变量SRC_LIST
AUX_SOURCE_DIRECTORY(. SRC_LIST)

#生成应用程序hello(在windows下生成hello.exe)
ADD_EXECUTABLE(hello ${SRC_LIST})

 

3. 运行cmake命令生成MakeFile，再运行make命令生成hello可执行程序（为防止文件混乱，可建立build目录，在此目录下运行cmake命令）
