Interest for adding CMake

[flriancu]

Hello @AndrewBelt ,

I am experimenting with your library for potentially including it in multiple projects, including industrial and academic. I would like to know if you are willing to consider a PR that includes CMake support plus some very minor fixes. I already have something I'm fairly content with, tested on multiple compilers on Windows and Linux, and I am working towards getting access to a macOS environment to complete my testing.

Please let me know if I should pursue this potential PR any further. Thanks!

Just after testing on macOS, I realized that there was already a pending CMake pull request. Let me know if I should file my own anyway. Thanks!
