# Translation pipeline.
#
# qt6_add_translations() runs lupdate against the target's sources (keeping
# the .ts files below in sync) and then runs lrelease to compile them into
# .qm files. The .qm files are embedded under the ":/i18n" resource prefix,
# where installTranslators() in main.cpp looks them up at runtime.
#
# The .ts files are intentionally shipped empty: translators are expected to
# fill them in. Re-running cmake / building the target refreshes the entries
# found by lupdate without dropping already-translated ones.
