+Subject: [PATCH] common: utils: Use include/ directory to get
+ <nbdkit-plugin.h>
+
+This worked before because nbdkit was installed by the system package
+manager, but if not:
+
+  utils.c:42:10: fatal error: nbdkit-plugin.h: No such file or directory
+     42 | #include <nbdkit-plugin.h>
+        |          ^~~~~~~~~~~~~~~~~
+  compilation terminated.
+
+Fixes commit 96b468d2e4214d15d722bd44db289d95e137280a.
