Setting environment variables doesn't work. First you have to set the
variables LUAINPUTS and CLUAINPUTS
in your texmf.cnf. Then you need luapackageloader to set the search
path correctly.
local loader = require('luapackageloader')
loader.add_lua_searchers()
If you are running texlua you have to set the program name correctly:
kpse.set_program_name('lualatex')
