If you are getting this message because the executable is added in the 
parent of the directory where the library is added then this can be 
fixed now when using the CVS version of CMake.  Look at the 
ADD_SUBDIRECTORY command.  It lets you do in-order subdirectories 
instead of post-order and should resolve this problem.
