Hi Francesco,

The solution I use for click tracks uses this:

https://lists.gnu.org/archive/html/lilypond-user/2019-12/msg00346.html

That will give you a definition of clickTrackForMusic. All you need to 
do then is to provide the time signature and the music.

When I use it I do this:

-----

clickPart = \clickTrackForMusic \timeSignature \music

% Click track:
clickStaff = \new DrumStaff = "click" {
  \set DrumStaff.instrumentName = #"Click "
  \clickPart
}

-----

It automatically adjusts the length of the click track to the length of 
the music, but does not handle changes of time signature or tempo.
