it seems that your executable is trying to link to the dynamic library libatomic.so which cannot be found in you file system default path under /lib so either import it manually to this placement or if you can use a static link method in your QT project to ensure that your executable can run in a standalone mode.
You can list the shared library dependencies which your executable is dependent upon. The ldd <name-of-executable> command does that for you.
you can add the libatpomic.so by following this guide (see Include a prebuilt shared library) .
