This did not work in the old generator.  Creating custom make targets 
with "#" in the name looks dangerous.  Each make program will want its 
own kind of escaping.  It could probably be done but might cause 
trouble.  I think the best way to resolve this issue is to make 
ADD_CUSTOM_COMMAND and ADD_CUSTOM_TARGET give an error if the output has 
a "#" in its name.
