windeployqt path with multiple QT kits

I have anaconda2 installed on my pc in its own folder and a separated installation of qt in another.

Now I am trying to deploy an application using:

C:\Qt\5.11.0\mingw53_32\bin\windeployqt.exe my app.exe -qmldir=myqml directory

This used to work perfectly before installing anaconda. Now this command returns:

QML imports:
   'QtQuick' C:\Users\me\Anaconda2\Library\qml\QtQuick.2
   'QtQuick.Window' C:\Users\me\Anaconda2\Library\qml\QtQuick\Window.2
   'Qt.labs.settings' C:\Users\me\Anaconda2\Library\qml\Qt\labs\settings
 Direct dependencies: Qt5Core Qt5Gui Qt5Qml
 All dependencies   : Qt5Core Qt5Gui Qt5Network Qt5Qml
 To be deployed     : Qt5Core Qt5Gui Qt5Network Qt5Qml
 Unable to find the platform plugin.

 Windeployqt should be searching qml plugins in C:\Qt\5.11.0\mingw53_32\ instead.

I wonder what is causing this kind of behavior. There may be an option to force the plugin path on windeployqt.
