Thanks, Ivan. While this is true for other libs like xcb, Qt does not ship
icu. It uses either the one provided by the system or a thin replacement
resulting in a reduced localization feature set according to
https://wiki.qt.io/Qt_5_ICU#Design_Principles

I am a bit confused by "-R .". after reading the documentation:

        -R <string> ........ Add an explicit runtime library path to the Qt
                             libraries.

I thought that "." is always implicitly the first path where the run-time
linker looks for (other)libraries. So I don't understand why it is set
explicitly.
