Subject: CMake: use GNUInstallDirs for library install dir
X-Git-Tag: v1.3.4~1^2~81^2
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=403e2db139d81a00a5b2da10d22dec56e41225c4;p=thirdparty%2Fzstd.git

CMake: use GNUInstallDirs for library install dir

Libraries now will be installed in the correct directory on x86_64 linux systems,
and can be changed with `-DCMAKE_INSTALL_LIBDIR=<dirname>` option.
