On the machine you compile the code and where this library is present a
call to

pkgchk -l -p <path>/libXcomposite.so.1

should report you where this file came from.
But you claim that this file isn't present on your development machine.
This make the problem a bit harder. Did you recompile Affiche on this
machine or copy it over from somewhere else?

What you can do is run ldd against Affiche:
ldd Affiche.app/Affiche

This will report all the libraries this executable has been linked against.

The libXcomposite is part of the composite manager for X11, this isn't
used directly in GNUstep. It either may be used by Affiche or by a theme
you are using.
