So I was able to set up a MyApp.app bundle using MACOSX_BUNDLE using these: https://github.com/OpenHantek/openhantek/issues/229
https://github.com/euler0/mini-cmake-qt
The current step is running macdeployqt MyApp.app to handle all the target libraries and plugins.
However, when I run macdeployqt, it's trying to find some sql libraries, and threw errors because there is no sql. The problem is that my project is not using sql at all.
The libraries I'm using are Core Gui Svg Widgets WebView WebEngine WebEngineCore WebEngineWidgets Concurrent Test
