How to make WebPack copy a library instead of bund

Question

I have a project that imports a few libraries I have installed with npm:

import {obj1} from Lib1;
import {obj2} from Lib2;

Is it possible to configure WebPack to skip Lib1 from bundling and copy the entire library instead to the output folder? If you're curious why I need that, the library contains a .proto file which is skipped during the bundling, which breaks the execution.
