Qt application cannot find shared library at runtime

I'm using Qt Creator to build a GUI application, which depends on some extra libs. It works quite well when I run the application from Qt Creator. But while I try to start the application by double-clicking or from console, I found it failed to find those libs. In my .pro file, I configured the lib directory as follows:

MYDLLDIR = $$OUT_PWD/libs
INCLUDEPATH += $$MYDLLDIR
win32:LIBS += $$quote($$MYDLL/test.dll)
unix:LIBS += $$quote(-L$$MYDLLDIR) -ltest

My test.so and test.so.1 and all others are under libs directory in my output folder. How can I make it to find those libs also during runtime? Thank you.

Extra Note: I'm running under Ubuntu 16.04.

There are many possible solutions.

You can install your shared library to standard locations like /usr/lib, /lib or /usr/lib64 etc.

Or before running your application from console, you can set the LD_LIBRARY_PATH environment variable to include the directory which contains your shared library.

See this link for details.
