How to add a specific folder to external option?

[chrber04]

Hi, just recently started using tsup and I was curious how you add a specific folder to the external option?

We have a 'generated' folder and would like to exclude just this folder. It's at the same level in the directory as the tsup.config.ts file.

Right now we exclude it with the RegExp /generated/

This caused issues with alias paths however, when we name our alias path @generated/*...

Thanks!
