Installation on Ubuntu Studio 23.04

[Wattbag]

Hi, "make" command gives this result on my Ubuntu :

In file included from src/uris.c:9:
src/uris.h:12:10: fatal error: lv2/lv2plug.in/ns/ext/atom/atom.h: Aucun fichier ou dossier de ce type
12 | #include "lv2/lv2plug.in/ns/ext/atom/atom.h"
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

And no .lv2 is created... maybe I should run make anywhere else ? Thx
