FYI
I have managed to get the IDE (1.9.0) to compile and run using QtCreator 4.6.1. and QT 5.5.1 under opensuse Leap 42.2.
Obtained code using git clone --recursive https://github.com/openmv/openmv-ide.git
This includes being able to update the example ode and updating the firmware.
This is using an OpenMV M7 board.
