# FindLua51
# ---------

#
# Locate Lua library This module defines
#
# ::
#
#   LUA51_FOUND, if false, do not try to link to Lua
#   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/
