Add/improve build instructions

[ronso0]

Fiddling with EasyStroke I discovered this fork and want to give it a try, though build instructions are missing.
I mean, I see it's c++ and the latest .vscode commit mentions cmake, but more explicit instructions would be nice.
Thanks!

I figured out what the problem could be. I've started modifying the build shell for Linux to include verbose descriptions of what's going on when the user runs the build script.

I'm adding a few more quality of life improvements to help users understand what's going on as the project installs.
