The path is somewhat standardized between all distros. There are some distros (like Arch) that simply don't have this file because they use different upstream source (gentoo vs. fedora) that is missing that but from I can tell they still use /usr/share/hwdata for all distros I checked. I can add a cmake check if you want. dvratil: The path is somewhat standardized between all distros. There are some distros (like Arch) that… | |||||
Yep, I would prefer this. Just to also make clear at compile time that it's missing. I don't like hidden dependencies which fail on some distros. graesslin: > I can add a cmake check if you want.

Can we be sure this path is the same on all distros? Should we runtime depend on it? E.g. a cmake check whether it's available?
