Subject: fix: ignore non-existent properties during header generation

`get_target_property(<var> ...)` sets `<var>` to `<var>-NOTFOUND` if the
property doesn't exist for the given target.  Detect this situation to
avoid adding various `-Dprop-NOTFOUND` and `-Iprop-NOTFOUND` to the
command-line when generating the headers.
