Surely not given that you're generating the module by compiling code.
/usr/lib/lua/5.1, perhaps?

luadir = $(LUA_DIR)
lua_LTLIBRARIES = cairo.la

and then set LUA_DIR as an AC_SUBST variable in your Autoconf
configure.ac, which can then apply platform-specific logic, use a --with
flag to specify the path, etc.
