They are documented in the qmake manual.
I found the solution after more digging into the qmake variables documentation
and some tests.
Do not manually add the qm-files to the qrc file. Instead add following to the
*.pro file:
CONFIG += lrelease embed_translations
which will embed the compiled translations into the resource prefixed by "/
i18n/". This prefix can changed by the variable QM_FILES_RESOURCE_PREFIX.
In the code you can access the file under ":/i18n/app-de_DE.pm".
Hope that help others.
regards
Petric
