I'm wrong. It is with part of the dependency analysis work. In
particular, we tried to avoid duplication of the link line caused by
calling LINK_LIBRARIES after an ADD_EXECUTABLE. (Recall calls to
AddGlobalLinkInformation.) I was trying to be efficient and use a set,
which caused duplicates to be removed!

Perhaps the fix is to assume that global link libraries are always
added, never removed? That is, when merging in the latest global link
libraries,

function   MergeLibraries( globalLibs )
   Iterator i=globalLibs.begin();
   i += prevLibs.size();
   add( i, globalLibs.end() );
   prevLibs = globalLibs;

Is this a valid assumption?
