   9 With datadir outside of prefix (currently unsupported by Meson[1]
  10 but a frequent occurrence in Nixpkgs), the `datadir` entry,
  11 in the `polkit-gobject-1` pkg-config file will be an absolute path.
  12 This will prevent changing the base directory of `policydir`
  13 with `--define-variable=prefix=…`, which many projects use
  14 to install policy files to their own prefix.
  15
  16 Previously, this worked without changes on Nixpkgs’s part because
  17 the pkg-config template used by Autotools contained `@datarootdir@`,
  18 which resolves to `$(prefix)/share`[2], taking no heed of the changed datadir.
  19
  20 Similar issue can happen when a distribution package redefines datadir
  21 like Debian does/did.[3]
  22
  23 This patch changes Meson-based build system to use `$(prefix)/share`
  24 in the generated pkg-config files, mirroring Autotools.
