Symbol lookup error (undefined symbol) when deploying Qt5 app on clear Ubuntu machine

Set LD_LIBRARY_PATH the same way as your start script would do, e.g. by commenting out the line that launches your application and then sourcing the script.
The run ldd on the executable and see if it indeed sees all the libraries you have bundled.

when I run ldd with setted LD_LIBRARY_PATH variable:

LD_LIBRARY_PATH=. ldd app

LD_LIBRARY_PATH=. ldd app

To copy to clipboard, switch view to plain text mode 

I don't have not found libraries

I am not sure what you mean with that last sentence.
Does ldd not find any libraries, or does it find all?
