I try to ignore the error message above. I build a simple CMakeLists.txt cmake_minimum_required(VERSION 3.20)

I think it is related to this error when I build |

The order of linking of libraries is very important. Now I have a view errors: I tried to solve them by adding target_link_directories(app PRIVATE C:/Qt/Tools/OpenSSL-1.1.1j/Win_x64/bin/ssl_1.1/x86_64)

target_link_options(app PRIVATE -static-libgcc -static-libstdc++)This is my step by step guide to install SDL3 on Windows but it can be useful for MacOS too if you need a window Setting up SDL3 for Windows using CMake and MinGW-w64 You can draw GUI using ImGUI and SDL3: Building ImGUI statically and setting up it to the CMake project Server: app.js const WebSocket = require('ws');
const wss = new WebSocket.Server({ port: 8080 });
wss.on('connection', (ws) => {

ws.on('message', (message) => {

() => {
console.log('Client disconnected');

Nice, thanks for sharing. There should be an mbedtls version detection blob somewhere, as the API changed in 3.xxx. cf c27f5a9 |
