I was able to add OpenCV and Dlib into Unreal engine 4.25 and everything is working as expected.
The build of the project is completed successfully but when I open the project i get this wired error:
Assertion failed: png_ptr
[File:D:/Build/++UE+Licensee/Sync/Engine/Source/Runtime/ImageWrapper/Private/Formats/PngImageWrapper.cpp] [Line: 427]
When I build with only OpenCV everything is ok but when I add the Dlib I get the above error.
I have to say that this is an empty ThirdPerson Template and I didn`t import any png files and there are non in the lib…
What could cause this issue? how could I investigate it better? there is also no information in the log files…
