Loading shared library to debug with executable

What i am doing basically is building shared library and linking it to my executable. Project build and runs just fine. But when it come to debugging i can't do it (---If i debugging executable alone, there not problems, i can debug and everything works). Problem appears when i am launching debbuger. This is output with logging:

Should i include my library (*.so) file to 'launch.json'? or am i doing something not correctly?
