Subject: [Buildroot] [git commit branch/2021.02.x] package/sdl2: kmsdrm needs GBM
Date: Mon, 6 Sep 2021 17:39:44 +0200	[thread overview]
Message-ID: <20210906154103.D40AA886F7@busybox.osuosl.org> (raw)

commit: https://git.buildroot.net/buildroot/commit/?id=32ffddf0bb81200c607bb621b714294da19321c7
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2021.02.x

kmsdrm needs GBM (and so mesa3d) since its addition in version 2.0.6:
https://github.com/libsdl-org/SDL/commit/56363ebf6124b345e1cfbd14fb6c0e654837910c

If libgbm is not found, kmsdrm will be silently disabled
