Describe the Bug

Using webpack's CompressionPlugin makes Next's build process fail with following error message

> Build error occurred
Error: Cannot find module 'webpack'

Full error log

This was working in Next v10.0.5. Note, I haven't found which is latest working version of Next.

Expected Behavior

To build and create the compressed files.

To Reproduce

1. Clone https://github.com/awareness481/Next-With-CompressionPlugin-bug
2. Install deps
3. Run npm run build
4. Observe failed build

I'm not sure if Next.js is expected to work with webpack's CompressionPlugin or webpack's core plugins, but it was working in earlier versions which is why I decided to file this issue.
