title: ld: library not found for -lrt
body: <p>I am trying to run a project that was made and works for Ubuntu but on Mac OS. And when I am doing the make I got the following error:</p>
  
  <pre><code>ld: library not found for -lrt
  clang: error: linker command failed with exit code 1 (use -v to see invocation)
  make[2]: *** [consumer] Error 1
  make[1]: *** [CMakeFiles/consumer.dir/all] Error 2
  make: *** [all] Error 2
  </code></pre>
  
  <p>I can't see any library with that name at thole project.</p>
  
  <p>Can anyone explain what it is and how to solve it?</p>
