+cmake (3.16.3-1.deb9moz1) jessie-backports; urgency=medium
+
+  * Mozilla backport for jessie.
+  * debian/rules, debian/control:
+    - Don't build against system libraries. libuv is missing on jessie, and
+      it's just simpler to disable the use of system libraries altogether.
+    - But still use system curl.
+    - Don't build a dbgsym package through dh_strip, that's not supported on
+      jessie.
+  * debian/compat: Restore a compat level of 10.
+  * debian/control: Remove versioned dependency on debhelper.
