Keeping libraries separate ?

I am working with both ATtiny85's and normal Arduinos but a few of the libraries are not cross compatible. Is there a way I could set up the libraries folder to have the ATtiny libraries separate from the full Arduino ones?

Maybe have separate copies of the IDE, with a different File:Prefreneces/path in each where the libraries are?

Could you put some of the libraries in a non standard location and call them with #include “path/to/myLibrary” rather than #include
