FindLua50
---------
Locate Lua library.
This module defines::
::
LUA50_FOUND, if false, do not try to link to Lua
LUA_LIBRARIES, both lua and lualib
LUA_INCLUDE_DIR, where to find lua.h and lualib.h (and probably lauxlib.h)
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/
