+Subject: [PATCH] Revert "Disable polkit support if libpolkit is not installed"
+
+This reverts commit 1194dec4f8f2d1b8bd14e1625f34418ecfce817e.
+
+Removing polkit support with -Dpolkit=auto when libpolkit is not
+installed, removes the whole interface. This makes it impossible to
+add polkit support as a runtime dependency.
+
+Bug: #167
+Closes: #206
