I am trying to use the asio library on Windows 10, here is a simple test code block:
#include <iostream>
#include <asio.hpp>
using std::cout;
int main()
{
std::cout << "hello asio\n";
asio::io_context ioc;
asio::steady_timer tmer(ioc, asio::chrono::seconds(1));
tmer.wait();
cout << "hi asio\n";
ioc.run();
return 0;
}
with Visual Studio 2017. To open a developer command prompt, I use the following command
C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\Common7\Tools>vsdevcmd
Then, based on the asio doc, I run the command nmake -f Makefile.msc
under the asio src folder. But I am getting an error:

Stop.
It seems the library requires boost/config.hpp. I really trying to avoid to use the boost. Is there a way I could use the asio standalone on windows 10?
I tried to use vcpkg, but it turns out I only need to download the library and create a cmake file to do the job.
cmake_minimum_required(VERSION 3.12)
project(asio)
