Error running build_prepare.py

[dmay31]

Trying to run build_prepare.py on windows and it can download
https://iweb.dl.sourceforge.net/project/libjpeg-turbo/2.1.3/libjpeg-turbo-2.1.3.tar.gz

I also can not get this file from a normal web browser.

The link is timing out for me as well at the moment.

You can download a cached copy from https://github.com/python-pillow/pillow-depends/blob/main/libjpeg-turbo-2.1.3.tar.gz and place it in Pillow/winbuild/depends to bypass the download. (You may have to create this directory first.)
