There's been various conversations on blog post comments, mailing lists and the forums to suggest there are people who want the ability to build Qt projects for Android and iOS using CMake (including myself). Which makes sense since this is a valid choice for desktop applications. I see a number of issues closed suggesting this is out of scope but I'd like to raise this as a suggestion so the community can at least vote/watch the issue.

This issues was originally raised against Qt rather than Qt Creator (which was pointed out to be wrong) https://bugreports.qt-project.org/browse/QTBUG-36384

https://bugreports.qt-project.org/browse/QTCREATORBUG-9341 - "We do not support using cmake for android development. No support is planned at the moment."
https://bugreports.qt-project.org/browse/QTCREATORBUG-9340

We have a large Qt4/CMake framework currently built for Win/Mac/Linux and the goal is to work out if we can also build and deploy to Android and iOS from a single codebase.
