It's probably clear already from looking at the branch, but my idea is this:


  "  $<TARGET_PROPERTY:prop>   = The value of the property prop on\n"   \
  "the target on which the generator expression is evaluated.\n"        \
  "  $<TARGET_PROPERTY:tgt,prop>   = The value of the property prop\n"  \
  "the target tgt.\n"                                                   \

I've updated the branch to implement the TODO I had left there for this, but 
I haven't tested it. It shows the intent, even if it has a bug :). 

Thanks,

Steve.
