+Subject: [PATCH] build/glslang: Fix build when OSDependent library is missing.
+
+The OSDependent glslang library is only available when it is built as
+a static library, not a shared one; look for the library but do not
+fail the  build when it doesn't exist.
+
+Fixes: <https://github.com/OGRECave/ogre/issues/3248>
