I cannot duplicate this problem from your example for CMake 2.0.2.  I 
get a Makefile for xlib that has the symbols defined when building the 
.o files, and a Makefile for aexec that has no mention of the symbols.

What version of CMake are you using?  Please post a complete minimal 
example that duplicates the problem.

Thanks,
