catch2/examples/120-Bdd-ScenarioGivenWhenThen.cpp
Martin Hořeňovský 44722f9ed3 Integrate CMake with <catch2/catch.hpp> include paths
This also goes for pkg-config installed by our CMake installation.

This includes

* Updating CMake version on Travis
* Adding a `Catch2` subfolder to the `single_include/` folder to
provide this include path both _inside_ the repository, and _outside_.
* Updated examples to build with the new paths
* Other general CMake cleanup
