如何使用CMake自动链接Boost库

Question

project(learn)

cmake_minimum_required(VERSION 3.11)

set(CMAKE_CXX_STANDARD 17)

if(${CMAKE_SYSTEM_NAME} STREQUAL "Linux")
    message("Current OS is Linux")
    include_directories("/mnt/e/c++/boost_1_72_0")
    link_directories("/mnt/e/c++/boost_1_72_0/stage/lib")
    link_libraries(pthread boost_thread boost_fiber boost_context)
elseif(${CMAKE_SYSTEM_NAME} STREQUAL "Windows")
    message("Current OS is Windows")
    include_directories("E:/c++/boost_1_72_0")
    link_directories("E:/c++/boost_1_72_0/stage/lib")
endif(${CMAKE_SYSTEM_NAME} STREQUAL "Linux")

add_executable(learn_asio learn_asio.cpp)

learn_asio.cpp：

#include <boost/asio.hpp>
#include <boost/fiber/all.hpp>
#include <boost/thread.hpp>
#include <iostream>

using boost::asio::async_write;
using boost::asio::buffer;
using boost::asio::io_context;
using boost::asio::use_future;
using boost::asio::ip::make_address;
using boost::asio::ip::tcp;
using boost::fibers::async;
using boost::fibers::fiber;
using boost::system::error_code;

int main(){
  io_context ioc;
  tcp::socket socket(ioc);

  tcp::endpoint ep(make_address("192.168.1.20"), 80);

  auto ret_f = socket.async_connect(ep, boost::asio::use_future);

  boost::thread_group t;
  t.create_thread([&ioc]() {
    ioc.run();
    std::cout << "jfiejf" << std::endl;
  });

  ret_f.wait_for(std::chrono::seconds(3));

  t.join_all();

  return 0;
}

我的图书馆文件夹：通过上面的代码，我可以成功地构建代码。但我讨厌代码：

link_libraries(pthread boost_thread boost_fiber boost_context)

在linux平台上。为什么在Windows平台上不需要它？我记得Linux也可以自动链接库。我该如何实现？
