# KI18N_INSTALL(podir)
# Search for .po files and scripting modules and install them to the standard
# location.
#
# This is a convenience function which relies on the following directory
# structure:
#
#  <podir>/
#    <lang>/
#      scripts/
#        <domain>/
#          *.js
#      *.po
#
# .po files are passed to the GETTEXT_PROCESS_PO_FILES function from the
# CMake Gettext module.
#
# .js files are installed using KI18N_INSTALL_TS_FILES.
#
# For example, given the following directory structure:
#
#  po/
#    fr/
#      scripts/
#        kfoo/
#          kfoo.js
#      kfoo.po
#
# KI18N_INSTALL(po) does the following:
# - Compiles kfoo.po into kfoo.mo and installs it in
#   ${LOCALE_INSTALL_DIR}/fr/LC_MESSAGES or share/locale/fr/LC_MESSAGES if
#   ${LOCALE_INSTALL_DIR} is not set.
# - Installs kfoo.js in ${LOCALE_INSTALL_DIR}/fr/LC_SCRIPTS/kfoo
