+Subject: [PATCH] doxygen/meson.build: remove dependency on doxygen binary
+
+New meson refuses to complete confuguration if doxygen is absent
+even if this target is never actually run. As we never run it,
+let's remove it, until upstream and/or meson figure out that it's
+optional and should be treated as such.
+
+Upstream-Status: Inappropriate [needs proper upstream fix]
