Set LUAINPUTS and CLUAINPUTS in texmf.cnf.
E.g.:

LUAROCKS_PATH = ~/.luarocks/share/lua/5.3
LUAROCKS_CPATH= ~/.luarocks/lib/lua/5.3
LUAINPUTS = $TEXMFDOTDIR;$TEXMF/scripts/{$progname,$engine,}/{lua,}//;$TEXMF/tex/{luatex,plain,generic,latex,}//;$LUAROCKS_PATH//
CLUAINPUTS = $TEXMFDOTDIR;$SELFAUTOLOC/lib/{$progname,$engine,}/lua//;$LUAROCKS_CPATH//
LUAINPUTS.lualatex =
$TEXMFDOTDIR;$TEXMF/scripts/{$progname,$engine,}/{lua,}//;$TEXMF/tex/{lualatex,latex,luatex,generic,}//;$LUAROCKS_PATH//
