Modules in Conan explained:

Building And Packaging C++ Modules In Vs2015

by Conan's blog

From the article:

This post makes a brief introduction to the C++ modules (we wished C++17, but we will have to wait). Modules have already been experimentally available in an early implementation in CLang, and now Microsoft is also providing them in Visual Studio 2015. We will see their syntax and how to build them, as introduced in the Visual Studio Blog, and at the same time, we will show how to create and consumes packages with C++ modules with conan C/C++ package manager.
