#
# This CMakeList handles the following i18n / language targets:
#
# - creating a translation test-tool
# - building the Python (gettext-based) translations
# - compiling all the Qt translations into a C++ file calamares-i18n.cxx
# - defines an OBJECT LIBRARY calamares-i18n for linking the compiled
#   translations into an executable.
