This is because EXPORT_LIBRARY_DEPENDENCIES is a "final pass" command 
that executes after all the rest of the configuration is done.  This is 
necessary to make sure all library linking is done before the command 
executes.  We should probably change the command to run immediately and 
document that the user should invoke the command in a CMakeLists.txt 
file that runs after everything else.  I'll discuss it with the other 
developers.
