how to pass a target:targetfile() to a configfile?

[Freed-Wu]

I try

  before_build(
    function(target)
          add_configfiles("rime.tmux.in")
      -- target:targetfile()
    end
  )

However cannot work.

[star-hengxing]

on_config(function (target)
    target:add("configfiles", "rime.tmux.in")
    target:set("configvar", "targetfile", target:targetfile())
end)
