Package
|
----bin
    |
    -----appli         


        

Answer 1

If you look at the output of your ls -al

These are soft links that you have. Your softlink libQt5MultimediaWidgets.so.5 points to libQt5MultimediaWidgets.so.5.9.2 in the same directory and the file is not there at all. So you need to either set the correct softlink path or have the file in same directory
