Or, something like this:

```
(define-public gobject-introspection+cairo
  (hidden-package
   (package
     (inherit gobject-introspection)
     (arguments
      (substitute-keyword-arguments (package-arguments 
gobject-introspection)
        ((#:configure-flags flags ''())
         `(append
           (list
            "-Dcairo=true"
            (string-append "-Dcairo_libname="
                           (assoc-ref %build-inputs "cairo")
                           "/lib/libcairo-gobject.so"))
           ,flags))))
     (inputs
      `(("cairo" ,cairo)
        ,@(package-inputs gobject-introspection))))))
```

Regards,
RG.
