title: RedisJson rejson.so file not created
body: <p>i am trying to setup Redisjson on redis-server</p>
  <p><em>git clone <a href="https://github.com/RedisLabsModules/rejson.git" rel="nofollow noreferrer">https://github.com/RedisLabsModules/rejson.git</a></em></p>
  <p><em>cd rejson/</em></p>
  <p><em>make</em></p>
  <p>after the make command i dont have a file called <em>rejson.so</em> anywhere however <em>make</em> command finished without error</p>
  <p>so that's why i cant load module to my redis</p>
  <p>i am using ubuntu 20.04
  i also have tried to clone from <a href="https://github.com/RedisJSON/RedisJSON.git" rel="nofollow noreferrer">https://github.com/RedisJSON/RedisJSON.git</a> and it didn't work either</p>
