this isn't supported by the internal data structures. By defining a 
VariantDir, you're creating an internal link between the source dir and 
the variant folder. Each Node (File or Dir) has only one "srcdir" entry, 
so several variant dirs can have the same source folder...but it's not 
possible the other way around.

I can only guess why this design was selected, but allowing more than 
one source folder would easily lead to problems when you have a 
subfolder with the same name. Let's say an "prog_a" folder would be 
present in "proj1" and "proj2", when both point to the same VariantDir.
How would you resolve this ambiguity?
