+# HOWEVER, in the GRIM reality of 2020, and now 2021:
+#
+# 1. The 2020.4 spirv-tools package in Homebrew doesn't bother installing the
+#    CMake config modules, so we have to find it the old way.
+# 2. The 2020.5 release has broken CMake config to the point of causing an
+#    *unrecoverable* CMake error. The only way to work around this is to
+#    override get_target_property() via a macro and insert an early-out for
+#    this case, then continuing to search the classic way. The 2020.6 package
+#    doesn't have this issue anymore but for some reason in certain cases
+#    Homebrew still gives people 2020.5.
 #
 # This module is thus *deliberately* called SpirvTools instead of SPIRV-Tools
 # to avoid conflicts with the upstream config file, if present.
