Simple questions from an ignorant person.

I am not sure how to install Qt for use on Android. For 
Subsurface-mobile to run on Android, where should Qt be installed?

Destination platform:
My intuition suggests to me that Qt-Android would need to be installed 
on native Android, but does this come across as part of the Subsurface 
application? I have never installed Qt on my Android device, yet I run 
Subsurface-mobile. Looks like the version for Android is Qt V5.7

Source platform:
What Qt version is required on the source (development) machine? I 
cannot see that Qt for Android would be required on the Linux source 
machine, unless this is somehow included as part of Subsurface-mobile? 
My Qt environment on Linux is 5.5.1

Kind regards,
willem
