I have been created (will be adding new features based on requests or if I found out any new idea) a completely compatible (with all the Arduino projects out of the box) simple package manager!
I would really appreciate if you could check and use if you like it!
You can find it here: GitHub - ksrichard/apm: Arduino Package Manager
A quick demo about that: https://asciinema.org/a/6L1JlVsEZMZdvUC8in2b4mjqc
