title: How do I cross compile QT application from ubuntu to windows?
body: <p>First I tried installing mingw and adding it to Qt creator's build kits, but I couldn't figure out how, and all the instructions I found on line just said it's easy without saying what to do. </p>
  
  <p>Next I tried using mxe, and I just get linker errors, mostly to do with zlib and freetype, but the linker flags for both are there, and it doesn't say it can't find the libraries.</p>
  
  <p>And while I can find similar errors in several stack overflow questions, none of them have answers.  So I'm at a loss, how do I do this?</p>
