title: Qt build warning: directory '/tmp/qt-stuff-6474/source/qt-everywhere-opensource-src-4.7.0/lib' following -L not found
body: <p>I'm trying to get a Qt app compiling for Mac running Snow Leopard, using Qt Creator 2.0.1 and Qt 4.7.0 (64 bit).</p>
  
  <p>The app compiles on other platforms, but on my Mac I get this warning</p>
  
  <blockquote>
    <p>:: warning: directory
    '/tmp/qt-stuff-6474/source/qt-everywhere-opensource-src-4.7.0/lib'
    following -L not found</p>
  </blockquote>
  
  <p>This is a new install of Qt Creator, and the .pro file contains no references to this directory.</p>
  
  <p>What causes this warning, and how might I correct it?</p>
