MAINT: new version of pkgconf-pypi broke the build #31129
Description
..\numpy\meson.build:185:4: ERROR: Problem encountered: No BLAS library detected! Install one, or use the `allow-noblas` build option (note, this may be up to 100x slower for some linear algebra operations).
Seems to have started failing yesterday.
Ping @mattip do you have any idea what's up with this?

It looks like pkg-config is not being picked up. Fix is in #31139

I meant to look into the new version. It added an environment variable specifically for our use case, which should enable using it instead of the choco version in the windows wheel build. Reopening, and changing the title

We worked around that issue quite easily in scipy-release, installing it in the cibw_before_build script.

I think #31152 will close this.

Closing, fixed by #31152.
