Hello, 

I was working with a personnal compilation of Qt 5.3.
Then I tried Qnx's compilation... impossible to run my application (called Screen) on my imx6 board:
This application failed to start because it could not find or load the Qt platform plugin "qnx".

Here is the output of the console using QT_DEBUG_PLUGINS = 1
