@sielicki:matrix.orgsielickithis is his first and only post on the cmake forums and it's <3'd by rob maynard who works at nvidia23:27:24
@sielicki:matrix.orgsielickii just kinda don't get the motivation, not really clear why the FHS steam shrinking needed this23:33:25
@sielicki:matrix.orgsielickibut who knows23:33:40
@sielicki:matrix.orgsielickias long as i'm stuck on my computer on a saturday, qq: is there a strong reason to hold cudart at 12.4 in master, or just nobody raised a PR for it? 23:39:13
@sielicki:matrix.orgsielicki https://github.com/NixOS/nixpkgs/pull/322075 looks like he just never got back to handling review comments :\ 23:40:51

@ss:someonex.netSomeoneSerge (back on matrix)I think the last comment in that discourse might be misleading23:41:13
@sielicki:matrix.orgsielickimaybe I did a poor job of summarizing it here in riot but that's what I expected to see23:42:13
@ss:someonex.netSomeoneSerge (back on matrix) Nvidia ships stubs without the .1s which is why we have https://github.com/NixOS/nixpkgs/blob/a8ffc2295c358629bc1bda569bf8b3bbb21aa1be/pkgs/development/cuda-modules/cuda/overrides.nix#L124-L129 23:42:54
@sielicki:matrix.orgsielickiThe problem I'm wondering about is what actually enforces that ld.so prefers /run/opengl-driver/lib to /usr/local/nvidia/lib64/stubs? or potentially someone's conda env or virtualenv23:42:59
