title: Need to integrate Wix projects into daily builds
body: <p>I need to integrate Wix projects into daily builds. I have followed following <a href="http://wixtoolset.org/documentation/manual/v3/msbuild/daily_builds.html" rel="nofollow">Link</a> and have set</p>
  
  <pre><code>&lt;WixToolPath&gt;E:\where\cplusplus\thirdparty\windows\wix\WiX Toolset v3.7\bin\&lt;/WixToolPath&gt;
  &lt;WixCATargetsPath Condition=" '$(WixCATargetsPath)' == '' "&gt;E:\where\cplusplus\thirdparty\windows\wix\v3.x\Wix.CA.targets&lt;/WixCATargetsPath&gt;
  &lt;WixTasksPath&gt;E:\where\cplusplus\thirdparty\windows\wix\WiX Toolset v3.7\bin\WixTasks.dll&lt;/WixTasksPath&gt;
  </code></pre>
  
  <p>When I build my project after having set above properties I see my project picking up <code>Microsoft.Deployment.WindowsInstaller.dll</code> from <code>C:\Program Files (x86)\WiX Toolset v3.7\SDK</code> instead I want it to be picked from <code>E:\where\cplusplus\thirdparty\windows\wix\WiX Toolset v3.7\SDK</code>.
  see output log: </p>
  
  <pre><code>Searching for custom action entry points in CustomAction.dll

    UnInstall=CustomAction!CustomAction.CustomActions.UnInstall
  </code></pre>
