Many many thanks John, this did the job :-)

However, I got:
Run-time dependency pycairo found: NO (tried pkgconfig, framework and cmake)

Thus I had to rebuild pycairo for Python 2 with the same extra option and it did the job:

% jhbuild shell
% cd pycairo-1.18.1
% mkdir build
% cd build
% meson -Dpython=python2 --prefix /opt/xnadalib-2020 --libdir lib  --wrap-mode=nofallback 
/opt/src-2020/pycairo-1.18.1
% ninja
% ninja install
% pkg-config pycairo --libs
% meson -Dpython=python2 --prefix /opt/xnadalib-2020 --libdir lib  --wrap-mode=nofallback 
/opt/src-2020/pygobject-3.32.2
% cd -
% cd pygobject-3.32.2
% cd build
% meson -Dpython=python2 --prefix /opt/xnadalib-2020 --libdir lib  --wrap-mode=nofallback 
/opt/src-2020/pygobject-3.32.2
% ninja
% ninja install

So, GNAT Studio (https://github.com/AdaCore/gps - IDE for Ada language) is running on macOS Big Sur!
Well, the mouse clic is weird: when clicking in a source code it selects many lines as shift key was pressed 
while clicking (text selection) !?

Kind Regards, Pascal.
