# This module creates build rules for updating translation files made
|
|
# with gettext
|
|
# In your top level CMakeLists.txt, do
|
|
# include(GettextTranslate)
|
|
# then in any po directory where you want things to be translated, write
|
|
# GettextTranslate()
|
|
#
|
|
# This module also finds the gettext binaries. If these are in a non-standard
|
|
# location, you can define the following variables to provide paths to search
|
|
# in
|
|
# GettextTranslate_BINARIES --- a path in which to look for every program
|
|
# GettextTranslate_XGETTEXT --- the xgettext program
|
|
# GettextTranslate_MSGINIT --- the msginit program
|
|
# GettextTranslate_MSGFILTER --- the msgfilter program
|
|
# GettextTranslate_MSGCONV --- the msgconv program
|
|
# GettextTranslate_MSGMERGE --- the msgmerge program
|
|
# GettextTranslate_MSGFMT --- the msgfmt program
|
|
# these are searched first before $PATH, so set this if you have your own
|
|
# version that overrides the system version
|
|
#
|
|
# it reads variables from Makevars, one of the most important being DOMAIN
|
|
# it reads the languages to generate from LINGUAS
|
|
#
|
|
# it adds the following targets
|
|
# lib-update-po
|
|
# lib-update-gmo
|
|
# ${DOMAIN}-pot.update
|
|
# generate-${DOMAIN}-${lang}-po
|
|
# generate-${DOMAIN}-${lang}-gmo
|
|
#
|
|
# where ${DOMAIN} is the DOMAIN variable read from Makevars
|
|
# and ${lang} is each language mentioned in LINGUAS
|
|
#
|
|
# if you want lib-update-gmo to be added to the "all" target, then define the
|
|
# variable GettextTranslate_ALL before including this file
|
|
#
|
|
# by default, the gmo files are built in the source directory. If you want
|
|
# them to be built in the binary directory, then define the variable
|
|
# GettextTranslate_GMO_BINARY
|
|
|
|
|
|
|
|
# add the lib-update-po and lib-update-gmo targets, the actual files that need to
|
|
# depend on this will be added as we go
