title: How to configure Jenkins to build solutions with Qt?
body: <p>I'm about to switch from CruiseControl.NET to Jenkins. </p>
  
  <p>My problem with the build process is the error "<strong>QtMsBuild: could not locate qt.targets, qt.props; project may not build correctly</strong>."
  I have already tried several solutions but without success. Changing the build methods (<em>NAnt/MSBuild</em>) also produces the same error message. 
  In Visual Studio under Project Properties (<em>C/C++ > Additional Include Directories</em>) I noticed that <strong>QTDIR</strong> is not known although it exists as an environment variable (as an example instead of {QTDIR}\include I only get \include). </p>
  
  <p>I am using:
  Qt 5.9.0, MS Visual Studio 2015, Qt Visual Studio Tools (V2.3.2)</p>
  
  <p>In the past I have tried on using an older version of the Visual Studio Tools plugin how the developers recommend. I also checked the paths and set environments variables. Giving Jenkins the path  "<em>C:\Users\user\AppData\Local\QtMsBuild</em>" as parameter does not changed anything. </p>
  
  <p>I do not want to copy the files from "<em>C:\Users\user\AppData\Local\QtMsBuild</em>" into each build directory, because at ccnet it's working. </p>
  
  <p>How can I solve this problem?</p>
