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
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
