Unable to build accelerate in Python 3.10

[EpicWink]

I'm trying to build pyopengl-accelerate from source with Python 3.10, but it fails

Reproduction

In the python:3.10-slim Docker image

apt-get update
apt-get install --no-install-recommends --yes gcc libc-dev
CFLAGS='-w' pip install pyopengl-accelerate

Output

...

It seems all of these suggest regenerating the C code with a newer version of Cython (v0.29.20 or newer)

Fixed with cee6534 and b485dde, released in v3.1.6

Hi guys, seems only Windows got v3.1.6 on the pip repository, but what about Linux users? Thanks~

$ lsb_release -d
Description:	Ubuntu 22.04.1 LTS
$ python3 --version

$ sudo pip3 install PyOpenGL-accelerate==3.1.6

For now, seems installing from git is the only way for Linux users.

sudo pip3 install git+https://github.com/mcfletch/pyopengl.git@227f9c66976d9f5dadf62b9a97e6beaec84831ca#subdirectory=accelerate

@cv3d See #78, and could be fixed by #84 or #85
