+# LUA_LIBRARIES
+# LUA_INCLUDE_DIR, where to find lua.h
+# LUA_VERSION_STRING, the version of Lua found (since CMake 2.8.8)
+#
+# Note that the expected include convention is
+# #include "lua.h"
+# and not
+# #include <lua/lua.h>
+# This is because, the lua location is not standardized and may exist
+# in locations other than lua/
