[Clion build] Implemeted CMake build for easier debugging

[EmmanuelMess]

I am working with CLion and it really likes CMake, so I made an implementation.

This -> #29 and this #45

A similar build option has already been proposed for the entire project (including the whole demos), but was rejected due to the preference to the Makefile. I am not sure that this will be accepted. But I'm sure it will come in handy for someone

P.S.
The closed ones (issue / pull-req) contain snippets of code and various useful references as in the repository. Despite the fact that they were not accepted into the main tree of code, they can be useful.

Of course, this is not for me to decide. But I just warned about the specifics of accepting and rejecting merge requests.

P.P.S
If I were you, I would add to the heading "Clion build" the people who use it and find it will thank you
