Compile to android without qtcreator

[suizokukan]

Hello,
I have a Qt5/C++ "project":https://github.com/suizokukan/dipylonreader written for Linux and Windows. Everything's fine with the (Linux) command line and I can produce binaries for these two platforms using only tools like gcc and qmake.
Now, I want to compile my project for Android : everything's detailed "here":http://qt-project.org/doc/qt-5/deployment-android.html but I don't want to use qtcreator in order to automate the different builds.

I read "in these old thread":https://groups.google.com/forum/#!msg/android-qt/fdoBDyeBunI/EQJBHymUmJ8J that it wasn't possible one year ago.

Is this still the case ? Is there a tutorial available somewhere ?

Any help would be appreciated !
