Running command:

шоу that/usr/lib/debug/opt/qt55/lib/libQt5Core.so.5.5.1 is present. But I don't know how to make qtCreator to соединение to it using Debug configuration (using qmake and cmake).

I am sure that correct "Кт Версион" is selected. Модулируй View in debug шоу that libQt5Core is loaded from/opt/qt55/lib/libQt5Core.so.5

I tried to run:

source /opt/qt55/bin/qt55-env.sh
