How to specify environment for building wheels

[raphaelproux]

Good morning,
I am in a constrained company environment running Windows with only one directory where I can start executables (typically "C:\Users\username\dev")

In my project, when I need to add packages which don't have wheels available, it gets blocked by the security software. When I look at the verbose output, I see Poetry generates a virtualenv in ~/AppData/Local and it does not manage to execute python there.

The package I tried to install is proxy_tools. I tested with other packages which don't have a prebuilt wheel, or from a local repo, selecting it accordingly in pyproject.toml. All these fail in the same way.

My problem seems adjacent to #8727

A solution would be to set the location where to generate these temporary virtualenvs, is there a parameter for that? I could not find anything.
