Don't know.
I think it is enough to include both libraries into the corresponding search paths.
Especially for simulation make sure you have included the necessary model libraries:
You can have as many foundry PDKs as you like. But only
one per project (library setup is project specific). Project
home will likely also want links to layers and rules files. The
setup of PDKs is also foundry-idiosyncratic to some extent
but each kit should document how to set up all of the
links and such.
