今天在网上看到了C++，socket编程的代码，心血来潮想要试一下，复制到本地项目后运行报以上错误，
实验环境
clion 2021.1.3编译器
cmake版本3.17
Mingw编译器 8.1版本
根据报错显示是我们的链接错误，windows上的socket编程需要链接库ws2_32 wsock32
解决方法
在cmaklist.txt文件中加上
link_libraries(ws2_32 wsock32)
例如：我的cmakelist.txt文件
cmake_minimum_required(VERSION 3.17)
project(mutil_thread_ope)
set(CMAKE_CXX_STANDARD 14)
link_libraries(ws2_32 wsock32)
add_executable(mutil_thread_ope main.cpp Server/ope_server.cpp Server/ope_server.h Client/client.cpp)
add_executable(client Client/client.cpp)
add_executable(ope_server Server/ope_server.cpp)
