I was trying to propagate SET_SOURCE_FILES_PROPERTIES to a 
subdirectory.  For GENERATED this makes sense, as files typically have 1 
point of generation.  So, it would be reasonable to set GENERATED once 
at the place they're generated, rather than several times wherever they 
are consumed.  I am not sure if directory propagation would be 
reasonable for other properties though.  Is this worthy of a feature 
request, or is it not doable / adviseable?
