Show build output when building an extension package

[julian-smith-artifex-com]

Is there a way to make Poetry show the build output when poetry add builds an extension package?

I've tried various combinations of poetry -vvv add, poetry add -vvv, poetry -v -v -v add -v -v -v, and tried to look for a log file somewhere, but without success. All i see is various diagnostics then:

[build:build] Building wheel...

At this point running ps shows various compile and link commands are running so it looks like Poetry is building the project, but the output is not showing.

The command i'm running is: poetry add -vvv "git+https://github.com/pymupdf/PyMuPDF.git". The build is quite complex and we have customer reports of it not working, so i'm trying to reproduce the problem locally.

poetry --version says: Poetry (version 2.1.1); i'm on Linux.

Thanks in advance for any suggestions.
