I pip install a specific package with --global-option. How do I add that package as a dependency in setup.py?

Question

I'm using this package called Dulwich. While developing, I install it like this:

pip install dulwich --global-option="--pure"

I want to add dulwich as a dependency to the setup.py file for my own package, but i'm not sure how to get it to use that pure flag. If my dependencies just looks like this:

DEPENDENCIES = [
    'dulwich',
]
setup(
    install_requires=DEPENDENCIES,
    ...
)

it will fail. I've tried all variations of adding --pure and --global-options but they all fail with errors like:

'install_requires' must be a string or list of strings containing valid project/version requirement specifiers; Invalid requirement, parse error at "'--pure'"

How am I supposed to correctly add this package as a dependency? The end goal is that I can put my package on PyPi, so that when someone runs

pip install my_package

it will automatically run the equivalent of pip install dulwich --global-option="--pure" as well
