The Porter's Handbook section 6.5.4 "Using cmake" references a deleted port deskutils/strigi as an example.
Given this port is no longer available, this example should either be removed or an alternative port should be referenced as an example.
Add cmake's maintainer to see if they have a preference on how to address this.
I would suggest to just remove the '(see deskutils/strigi for an example)' from the handbook.

If you prefer to keep an example, I would suggest `devel/kf5-kcrash'.
It has a very small plist at the moment (13 lines), and uses the sub.
