Naming convention for libraries

[JasonMarechal25]

Currently we have mix naming for libraries.
Libraries are typically named after there directory or existing naming. This lead to some inconsistency.

This lead to three questions:

• Which convention for directories ? (PascalCase, camelCase, snake_case, kebab-case, flatcase, Capitalised_Snake_Case, Capitalised-Kebab-Case)
• Which convention for libraries ?
• Should libraries and directories follow the same convention ?

I'd personally go with kebab-case for CMake targets & directories
