Please follow the my_app/README.txt (which assumes that your lisp files are in my_app/lisp/)
The dependencies are:
eql5, ecl, Qt5Core, Qt5Gui, Qt5Widgets, Qt5PrintSupport shared libraries (plus used modules, both Qt5 and EQL5)
*.ui files (if any)
*.qm translation files (if any)
[Unix]
Deploy the installed libraries from /usr/local/lib/, because they have already been stripped, and are therefore smaller.
A detailed description of deploying Qt applications can be found in Qt Assistant (see especially windeployqt and macdeployqt for those specific platforms).
Since some steps in this process may not be obvious, here an example of a simple/basic deploy.bat script for the Windows platform:
mkdir setup
mkdir setup\encodings
del setup\my_app.exe
copy c:\ecl\msvc\package\ecl.dll setup\
copy c:\ecl\msvc\package\encodings\*.* setup\encodings\
copy c:\eql5\eql5.dll setup\
copy c:\eql5\eql5_quick.dll setup\
copy c:\eql5\eql5_network.dll setup\
copy release\my_app.exe setup\
windeployqt.exe --release --qmldir ./qml setup/my_app.exe
windeployqt.exe --release --qmldir ./qml setup/eql5.dll
windeployqt.exe --release --qmldir ./qml setup/eql5_quick.dll
windeployqt.exe --release --qmldir ./qml setup/eql5_network.dll
