@JamesBallard1, currently I'm working for Oak Ridge National Laboratory, we have many projects that are interconnected and use TriBITS and CMake for package management and configuration. We've avoided .pro, .qml, and qmake. I'm not sure of the history, whether it's for our CI, static analysis tools, security scans, legacy developer preference, or something else entirely.
I've updated a widget from QMapControl (because ArcGIS is superior) last year and everything's been great for Windows and Linux. Now we're interested in Android, and used https://github.com/LaurentGomila/qt-android-cmake with minor tweaks to easily generate our APKs.
I hope it's not much of a lift, and appreciate your consideration even if the request won't be accommodated.
Much appreciated,
Tom
