# Locate Lua library
# This module defines
# LUA_FOUND, if false, do not try to link to Lua
# LUA_LIBRARIES
# LUA_INCLUDE_DIRS, where to find lua.h
# LUA_VERSION_STRING, the version of Lua found
#
# 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/
