Implement libzstd feature check, NO_LIBZSTD and LIBZSTD_DIR defines to override Zstd library sources or disable the feature from the command line: $ make -C tools/perf LIBZSTD_DIR=/path/to/zstd/sources/ clean all $ make -C tools/perf NO_LIBZSTD=1 clean all Auto detection feature status is reported just before compilation starts. If your system has some version of the zstd library preinstalled then the build system finds and uses it during the build. If you still prefer to compile with some other version of zstd library you have capability to refer the compilation to that version using LIBZSTD_DIR define.
