+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

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
