This is the userspace part of drm, right? Can't we port the Bincrafters recipe for it?

What is the relationship between xorg and drm?

yes, and yes we could, but I'm afraid we'll get back to the problems we had with x11 packages, which led us back to system packages instead of conan built packages. https://gitlab.freedesktop.org/mesa/drm says New functionality in the kernel DRM drivers typically requires a new libdrm, which could be interpreted as "you need to upgrade libdrm with each kernel DRM upgrade", or "you need to upgrade libdrm if you want to use a new feature of kernel DRM driver"

What is the relationship between xorg and drm?

I don't know, but I assume there is one, because apt already install libdrm-dev when installing xorg/system (it is an indirect dependency of xorg-dev)

All green in build 3 (d936de87157d7040383325204a6cc612157eeab2):

• xorg/system@:
  All packages built successfully! (All logs)

I asked the question about system package vs conan package upstream: https://gitlab.freedesktop.org/mesa/drm/-/issues/75

[ericLemanissier]

Please hold your reviews why we decide if it's system or not

[prince-chrismc]

Please convert as draft!

Thanks for asking upstream!

Independent from the question system package or not, I think that it should be separated from the xorg package. I believe that Wayland is using libdrm too
