# This script is created from the log of the windows build from windeployqt
# with Qt 5.12.1.
# From the log you can see which translation files are used which depends on
# which Qt modules we use.
# In our case these are qtbase_*.qm, qtdeclarative_*qm and qtserialport_*.qm.
#
# Note with Qt5 the Qt distributed qt_xx.qm files are metacatalogs, and just
# copying or converting them won't copy the dependencies.
