From 4d8de281b5834c8f5e0be6ae21e884e69dffd4ce Mon Sep 17 00:00:00 2001 From: Heikki Linnakangas Date: Sat, 27 Jul 2024 13:53:11 +0300 Subject: [PATCH] Fallback to clang in PATH with meson Some distributions put clang into a different path than the llvm binary path. For example, this is the case on NixOS / nixpkgs, which failed to find clang with meson before this patch.
