title: Qt and MacOs libiodbc.2.dylib and other libraries are missing
body: <p>I'm trying to make a <strong>macdeployqt</strong> using MacOs 10.13.6 with Qt 5.12.2 clang 64bit. When I runtime command:</p>
  
  <pre><code>/Users/developer/Qt/5.12.2/clang_64/bin/macdeployqt /Volumes/Condiviso/MyApp/build-MyApp-Desktop_Qt_5_12_2_clang_64bit-Release/MyApp.app
  </code></pre>
  
  <p>I get the following errors:</p>
  
  <pre><code>ERROR: no file at "/usr/local/opt/libiodbc/lib/libiodbc.2.dylib"
  ERROR: no file at "/Applications/Postgres.app/Contents/Versions/9.6/lib/libpq.5.dylib"
  </code></pre>
  
  <p>I already had problems with libmysqlclient.20.dylib but downloading the mysql plugin I managed to resolve that error.
  But for these two errors can somebody give me a suggestion or a link to find out how to resolve them?</p>
  
  <p>Thanks in advance!</p>
