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.
