 Keywords:          |       Port:  zstd
--------------------+--------------------
 Even after setting this, the build still leaves `zstd` build for the MacOS
 version it is running on:

 {{{
   echo 'macosx_deployment_target 10.13' | tee -a
 ${PREFIX}/etc/macports/macports.conf
   echo 'macosx_sdk_version 10.13' | tee -a
 ${PREFIX}/etc/macports/macports.conf
 }}}

 From `otool -l`

 {{{
 Load command 10
       cmd LC_BUILD_VERSION
   cmdsize 32
  platform 1
     minos 13.0
       sdk 13.3
    ntools 1
      tool 3
   version 857.1
 }}}
