多目录工程的CmakeLists.txt编写（自动添加多目录下的文件）

来源：互联网发布：悟空传知乎编辑：程序博客网时间：2024/05/21 06:29

实现类似于vs中工程的CMakeLists.txt的编写。功能为main.cpp调用hello.cpp 的hello()函数，world.cpp的world()函数。使用自动添加多目录下的文件

1.工程目录如下

这里写图片描述

2.主函数main.cpp

#include <stdio.h>#include "hello.h"#include "world.h"int main(){    hello();    world();    return 0;}

3.顶层CMakeLists.txt

cmake_minimum_required(VERSION 2.8)project(helloworld)# Add the source in project root directoryaux_source_directory(. DIRSRCS)# Add header file include directoriesinclude_directories(./ ./hello ./world)# Add block directoriesadd_subdirectory(hello)add_subdirectory(world)# Targetadd_executable(helloworld ${DIRSRCS})target_link_libraries(helloworld hello world)

4.hello文件夹

CMakeLists.txt

aux_source_directory(. DIR_HELLO_SRCS)add_library(hello ${DIR_HELLO_SRCS})

hello.cpp

#include "hello.h"void hello(){    printf("hello\n");}

hello.h

#ifndef HELLO_H#define HELLO_H#include <stdio.h>void hello();#endif

5.world文件夹

CMakeLists.txt

aux_source_directory(. DIR_WORLD_SRCS)add_library(world ${DIR_WORLD_SRCS})

world.cpp

#include "world.h"void world(){    printf("world\n");}

world.h

#ifndef WORLD_H#define WORLD_H#include <stdio.h>void world();#endif
