Effective Modern CMake

Effective Modern CMake

Getting Started

For a brief user-level introduction to CMake, watch C++ Weekly, Episode 78, Intro to CMake by Jason Turner. LLVM’s CMake Primer provides a good high-level introduction to the CMake syntax. Go read it now.

After that, watch Mathieu Ropert’s CppCon 2017 talk Using Modern CMake Patterns to Enforce a Good Modular Design (slides). It provides a thorough explanation of what modern CMake is and why it is so much better than “old school” CMake. The modular design ideas in this talk are based on the book [Large-Scale C++ Software Design](https://www.amazon.de/Large-Scale-Soft

Simple Async/Await Example
// 🔥 Node 7.6 has async/await! Here is a quick run down on how async/await works
const axios = require('axios'); // promised based requests - like fetch()
function getCoffee() {
return new Promise(resolve => {
setTimeout(() => resolve('☕'), 2000); // it takes 2 seconds to make coffee
});
