Qt static library in windows phone 8.1 application

Question

I have a Qt static library which I have linked to windows runtime component. I am using the runtime component in a windows 8.1 application. The whole set up compiles fine but if I use Qt types (like QString) in the Qt static library, the windows application crashes with the below error:

An exception of type 'System.IO.FileNotFoundException' occurred in SampleApp.exe but was not handled in user code

Additional information: The specified module could not be found. (Exception from HRESULT: 0x8007007E)

If I remove Qt types from static library and use only standard C++ types (int, wstring) the application works fine and does not crash.

Appreciate any help on how to fix this issue.

Found one solution to the issue.

Turns out windows app was not able to find Qt5Core.dll. The only solution to this issue I could find is to manually add this dll to windows app project in visual studio (Right click on project -> Add existing item) with 'Copy to output directory' property set to 'Copy if newer/Copy always'.
