Ah, I see. It appears I was unclear on the difference between target and

feature?
Generator expressions are generally only useful for things which are
determined at generate-time.
Can't you just read the test property at configure-time instead? You're the
one setting the property, right?
Deferring evaluation to generation time does have the advantage that you
can set and change properties at any point after the test has been
created and you can still be sure that the test is invoked with the
final value.
Without the generator expression reading the property at configuration
time is not really an option because the test's properties will not
exist before add_test() and the test command itself is what was
referring to that property.
You'd have to reorder logic so that the parameter for --skip-return-code
is known before add_test() (and use e.g. variables or (custom) target
properties).
