Missing wheel for netCDF4 1.7.4 for python 3.13 on Linux

[RRiva]

Hi, I've updated the dependencies of one of my packages, and now the CI on Linux fails with the following message, which happens on the Docker image python:3.13-bullseye. Can you please deploy the wheel for this configuration?

PEP517 build of a dependency failed

Note: This error originates from the build backend, and is likely not a problem with poetry but one of the following issues with netcdf4 (1.7.4)
  - not supporting PEP 517 builds
  - not specifying PEP 517 build requirements correctly
  - the build requirements are incompatible with your operating system or Python version
  - the build requirements are missing system dependencies (eg: compilers, libraries, headers).
You can verify this by running pip wheel --no-cache-dir --use-pep517 "netcdf4 (==1.7.4)".

P.S.: The Windows pipeline runs on python:3.13-windowsservercore, and there the installation works fine.

For the last few releases we have been providing ABI3 wheels, which are built for py311 but work for newer versions of python. You have to have a newer version of pip (or whatever other installer you are using) that supports ABI3 though.

Thanks, I'll open an issue on the Poetry repo. Nonetheless, I'm surprised that 1.7.3 installs just fine.

It could be that we have both non-ABI3 and AB3 wheels for python 3.11 and poetry is confused by that. pip seems to handle it fine.
