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

Let’s Encrypt is a free, automated, and open certificate authority (CA), run for the public’s benefit. Let’s Encrypt is a service provided by the Internet Security Research Group (ISRG)

About Let's Encrypt

This post won't go into details as to what Let's Encrypt is about. We should probably read the FAQs if we want to learn more.

Until the Google App Engine Team fully automate the process of using Let's Encrypt on Google App Engine or even provide some sort of API to handle certs, we'll probably have to find ways of either automating the process just a little bit or stick to some other easier cert authority.
