Thanks Thomas for you quick answer,

I did use "--with-shared" but as nothing happened I replaced it by 
"--with-ada-sharedlib".
With both of them the issue is still present.

Well, I remember an old GNAT issue with dynamic linking 
(https://github.com/AdaCore/gprbuild/issues/69), thus the following command 
does the job:

% LIBRARY_PATH=../../lib gnatmake -Padacurses.gpr -XBUILD_DIR=`cd ..;pwd` 
-XSOURCE_DIR=`cd ..;pwd` -XSOURCE_DIR2=`cd .;pwd` -XLIB_NAME=adacurses 
-XSONAME=libadacurses.so.1 -XLIB_KIND=dynamic -largs -lform -lmenu -lpanel 
-lncurses  
Build Libraries
   [gprlib]       adacurses.lexch
   [link library] libadacurses.dylib

I made the following changes:

diff --git a/Ada95/src/Makefile.in b/Ada95/src/Makefile.in
index db7100de..fee36483 100644

By he way, I was wondering why there are these warnings:
/bin/sh ./library-cfg.sh dynamic library.gpr -I. -I../include -I../../include  
-I/opt/xnadalib-2020/include -I. -I../include -D_DARWIN_C_SOURCE -DNDEBUG
