Cannot build against python 3.14 #665
Description
I can uv add ale-py with python 3.12 and 3.13 and it builds without errors. However on 3.14 I get the following error which seems related to SDL2:
Using CPython 3.14.0
Removed virtual environment at: .venv
Creating virtual environment at: .venv
Resolved 135 packages in 1.78s
× Failed to build `ale-py==0.11.2`
├─▶ The build backend returned an error
╰─▶ Call to `setuptools.build_meta.build_wheel` failed (exit status: 1)

help: If you want to add the package regardless of the failed resolution, provide the `--frozen` flag to skip
locking and syncing.
