### Problem description

When using pnpm, forge requires `node-linker=hoisted` in the project's .npmrc configuration. If the project is a monorepo with electorn inside e.g `root/app`, node-linker=hoisted means all node-modules are hoisted into the `root/node_modules`.
However electron-forge expects the node-modules to be present in the apps-root (`root/app/node_modules`) and therewith wont resolve native modules during build...

### Proposed solution

Support linked node-modules to be compatible with pnpm stores
