+Subject: [PATCH] glslang: update for new glslang versioning scheme
 
-    Hack around the newer glslang version scheme.
+This updates our checks to use the new header locations as introduced in
+https://github.com/KhronosGroup/glslang/pull/2277. Fortunately, it seems
+that the new version scheme is backwards compatible with the old one, so
+we don't need any excessively complicated logic updates.
+
+Fixes https://github.com/haasn/libplacebo/issues/83
