New issue by Frick-David on void-packages repository

https://github.com/void-linux/void-packages/issues/19670

Description:
Hey there,

I am using void linux (non-musl). I am trying to build [this](https://github.com/jonasmalacofilho/liquidctl)
repo for use on my computer. However, it fails with an error about missing Python.h header for hidapi, which I did not see a package for. Is there any chance this can be added for me. It would be sweet to get some RGB with my void linux.

In addition, is there any way I can also help build packages for others that need help. I want to help void linux grow, but am unsure how. For now, I am just trying to make PR's for documentation.

Comment:
`Python.h` is part of `python-devel` (2.7) or `python3-devel` (3.8).

Okay sweet, got it working. Thanks!
I will let the repo owners know as well!

Would this also build on musl?

From the  linked page:
If cython-hidapi is to be installed from sources or directly from PyPI, then build tools and **development headers for Python**, libusb-1.0 and libudev are also needed.

> Would this also build on musl?

"Packages are available for certain Linux distributions and package managers:
Alpine Linux: liquidctl"

Alpine uses musl, so yes.

I would guess they already know :-)

@jrigg Thanks, I did not see that. Very nice. This is a great little library. Is there any chance it could get packaged?

I am seeing that `python3-hidapi` or `python3-hid` were not previously packaged. I will probably go ahead and package it. Link to the repo here: https://github.com/trezor/cython-hidapi

Comment:
Per my discussion to package it:
```
- for a linux distro, you're going to need to build it linking to system hidapi (which is not its default)
- you need to pick which backends to enable (hidraw, libusb, or both)... default is both, but some distros may prefer only hidraw (which is the better one, unless hidraw is not available on that kernel for some reason)
- finally, if for some reason you need to override CFLAGS or anything like that, well, you may have issues with stuff being hardcoded in cython-hidapi's setup.py
again, the Arch PKGBUILD is a good reference, although they only build the hidraw backend and, like i mentined, this may not be the correct choice for void
regardless, be very careful that the build phase and the install phase are in sync in terms of which options you're sending to cython-hidapi's setup.py
(this is probably already handled by void, like options are only passed to build, and install uses the skip-build option... still, this is a common source of issues when building that lib with anything but its defaults options, which are not suitable for linux distros)
oh, the reason why you want to use system hidapi, instead of the default, is that the default is whatever hidapi version the project has pulled in... and no, then don't always stick to hidapi releases, in the past they have started to use a random commit
anyway: https://github.com/archlinux/svntogit-community/blob/packages/python-hidapi/trunk/PKGBUILD
```

``- Build it, linking to system hadapi
- Pick what backends to enable (hidraw, libusb, or both). Default is both, but some distros may use only hidraw.
- Look through cythonhidapi's setup.py if CFLAGS need to be overwritten
- Be careful that the build phase and the install phase are in sync in terms of which options being sent to cython-hidapi's setup.py to make sure it works (pretty new at this sort of thing, so will need to watch out as I feel this could be easy to mess up. )

- See Arch PKGBUILD for Cython-Hidapi (this does use the hidraw backend however, which Void may or may not follow) and other Void's package templates for examples

I know void does not need the arch anymore.
This is a python package so, I should reference a void python package for reference.
I can see it relies on udev, which might be tricky. I know void uses `eudev` and I am not sure if there is easy crossover there.
The license says `custom` I will need to look more into this.

The rest looks pretty straight forward unless I run into a problem with `eudev` or void does something entirely differently. We shall see.
