Hi,

I was trying to build TF-M with local libraries and noticed that patches were not applied in that flow.

I found an issue with fetch_remote_library() when using local library paths instead of downloading the dependency.

The function exposes LIB_FORCE_PATCH, and the documentation says it should control patching when the library source is provided as a local folder. However, in the current implementation this does not really work for local libraries.

We have our Modus Toolbox IDE which builds TFM as part of a project where all the libraries are already cloned, thus we need a way to forca patch local sources.

Is upstream community interested in this ? If so I can propose a fix soon.

A patch is available for review.

Best regards,
