Missing Qt plugin on Toradex iMX7D-512 with Toradex v2.3 SDK for WEC2013

The build completed. I copied everything to \FlashDisk\System. However, I now have the problem where trying to load any Qt app that uses any of the Qt DLLs throws up the error:

Note that this is not the path error that displays if the DLL is “not found”. It won’t “import” it.

This seems to be related to the -MT vs. -MD option during compilation in Visual Studio. I used -MT and did not have that issue, but -MD won’t work. Any hints as to why?

Thx
