Z the executable depends on X1.c, X2.c, Y1.c, etc, not X or Y as 
_executables_.  However, Z also depends on both the X and Y as _projects_.

If the result of project X isn't a stand-alone executable, but a shared object 
such as a library (zlib, GNU readline, libssl) or something like an Apache 
module (DSO's, aka dynamicly shared objects), Z the executable may well depend 
on libX.so.

At one time, the FSF found it useful to encourage a distinction between 
compiling source units from a GNU project into a staticly linked executable, 
and between dynamicly linking a LGPL library into a seperate program.  These 
two methods of using GPLed/LGPLed code had very different implications in 
terms of licensing.
