title: LNK1146: no argument specified with option '/LIBPATH:' error in Qt
body: <p>I imported my Qt application developed on linux to windows. Now when I build my project I am getting this error:</p>
  
  <pre><code> error: LNK1146: no argument specified with option '/LIBPATH:'
  </code></pre>
  
  <p>I created a new project on windows and it works perfectly fine. One of the possible reason that would cause this is having spaces in the project path,but there are no spaces in my project path.Could you let me know how I could resolve this issue.</p>
  
  <p>This is my .pro file:</p>
