+Subject: [PATCH] tracecmd: add NO_LIBZSTD option to disable libzstd
+
+Other Linux kernel tools like perf already include options to disable
+libzstd manually. Add this option also to trace-cmd.
+
+The OpenWrt SDK fails to build trace-cmd due to the autodetection of
+libzstd. The package is present in some feed repositories but should
+not be used by trace-cmd. The compilation will fail with:
+
+  Package trace-cmd is missing dependencies for the following libraries:
+  libzstd.so.1
