[Interest] Strange unexplainable RCC error

Mon May 27 07:14:06 CEST 2019

https://doc.qt.io/qt-5/resources.html
The resource files listed in the .qrc file are files that are part of the application's source tree. *The specified paths are relative to the directory containing the .qrc file.* Note that the listed resource files must be located in the same directory as the .qrc file, or one of its subdirectories.

IMHO, making paths in resource files relative to the current directory would be *really* strange and most unfriendly decision.
