Big thank you! It's awesome and works. I first misunderstood your link, I
thought I need some kind of Linux/and/or/Environment variables...

So here, for the records, a conditional include example + accessing a subdir:

#(if (= Clarinet 1) (ly:parser-include-string "\\include \"music/Clarinet-I.ily\""))

Best regards
