2 同文件夹多个编译

CMakeLists.txt

cmake_minimum_required(VERSION 2.6)
project(tcp)

#自动连接模式

#1将文件夹下全部文件链接到 src
#aux_source_directory(. src)
#将src里面的所有文件链接用于生成可执行文件
#add_executable(project1 ${src})      

#手动添加模式
#1测试-生成可执行文件main
add_executable(main src/main.cpp)

add_executable(client src/client.cpp)

add_executable(Server src/Server.cpp)

add_executable(http_client src/http_client.cpp)

 #设置可执行文件的输出目录
