How to build Android x86_64 app in Qt?

[Shah]

I installed Qt for Android (Windows x86), there is no Qt for Android (Windows x86_64) offline-installer. And I haven't an Android x86_64 complect to build my app for this target platform. I only started with Qt.
How can I add it? Or how can I install a Qt with an Android x64 support?
P.S. I can't use online-installer, it outputs network error always.

@Shah As far as I know where is not Qt Android x86_64 build available, even not with online installer. If you really need it you will have to build Qt by yourself.
