 The goal behind The Modern C++ Challenge project is twofold. On one hand, let users download, build, and execute the code with a minimal effort (ideally without needing to install any library). On the personal side, get some hands-on experience with _CMake_ and other tools of the C++ ecosystem. I've also taken the chance to improve the original code with:
 - _Tests_ (google tests).
 - _Benchmarks_ (google benchmarks).

+- _Static analysis_ (CLion's Inspect Code).
 - _Continuous integration_ (GitHub actions).
 - _Code coverage_ (gcov).
+- _Compiler caching_ (ccache).
 
 And I plan to better it further by using _sanitizers_.
