Subject: [PATCH v8 01/12] feature: implement libzstd check, LIBZSTD_DIR and NO_LIBZSTD defines
Date: Thu, 14 Mar 2019 14:28:18 +0300 [thread overview]
Message-ID: <c9c86021-7aa0-bbde-234d-9fcac5b82afb@linux.intel.com> (raw)
In-Reply-To: <4c037bbd-1cc9-90f2-b9cd-0e0839c83b73@linux.intel.com>
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.
