+Subject: [PATCH] Fix the link order of libglslang and libHLSL
+
+libglslang depends on libHLSL, so the latter needs to be specified last.
+This fixes an issue when trying to build shaderc against system-wide
+versions of libglslang/libHLSL, rather than the in-tree versions from
+third_party.
+
+Additionally, libshaderc_util also depends on SPIRV-Tools
