DUST

DUST (Driver UpdateS Tool) is designed to "just work" for building kernel driver modules. The concept is similar to DKMS, though this has the benefit of being simpler, easier to test and use, and easier to integrate. DUST enables you to package up a driver pack, install it into the dust directory, and prepare for upgrading. Each driver pack has 3 components: an install file (populates a tree with stuff needed to build a working driver); the driver payload (tarball, zip file, etc.); and the update script, which will do nothing but copy the old driver kernel modules to a backup directory, build/install a new copy of the driver kernel, run depmod if needed, and mkinitramfs, mkinitrd, or dracut if needed. The install file is very trivial. It is easy to recode this as an RPM or deb. As long as it moves the driver payload and update script to the right location, you can use any mechanism to do this.
