To allow for package transformations, I recommend using
this-package-input or the like instead of hardcoding a particular
package:

#~(list
    (string-append
      "-Dwith-usb-ids-path="
      #$(this-package-input "hwdata:usb") "/share/hwdata/usb.ids"))
    [...])

it might also be possible to use 'search-input-file' instead, avoiding
input labels (untested):

#~(let* ((inputs #$(input-tuples->gexp (package-inputs this-package)))
         (usb.ids (search-input-file inputs "/share/hwdata/usb.ids"))
         (pci.ids (search-input-file inputs "/share/hwdata/pci.ids")))
    (list (string-append "-Dwith-usb-ids-path=" usb.ids) [...]))

Greetings,
Maxime.
