Subject: [Buildroot] [PATCH v3 1/3] package/zstd: rework build and install
Date: Thu, 17 Jun 2021 11:14:50 +0200 [thread overview]
Message-ID: <20210617091456.272611-1-nolange79@gmail.com> (raw)
1.5.0 uses Threads by default for cli tool and DSO,
the build now does the same unless:
If only static libraries are build, then build
that library like the DSO is normally built.
This should ensure that programs requsting the DSO
will always get the multithreaded version.

* use normal = for assignment
v1->v2:
