There is an updated version now on stage.

The behaviour of cmExportBuildFileGenerator now basically is the same as it 
was before.
The collected target exports are not considered at all anymore, error handling 
and APPEND mode should work again exactly as before.
The code for handling missing targets has moved into a virtual function 
HandleMissingTargets(), which makes it IMO easier to handle all combinations 
correctly.
ComplainAboutMissingTarget() is not virtual anymore now.

The test works again as before.
