# - Find GNU gettext tools
|
|
# This module looks for the GNU gettext tools. This module defines the
|
|
# following values:
|
|
# GETTEXT_MSGMERGE_EXECUTABLE: the full path to the msgmerge tool.
|
|
# GETTEXT_MSGFMT_EXECUTABLE: the full path to the msgfmt tool.
|
|
# GETTEXT_FOUND: True if gettext has been found.
|
|
#
|
|
# Additionally it provides the following macros:
|
|
# GETTEXT_CREATE_TRANSLATIONS ( outputFile [ALL] file1 ... fileN )
|
|
# This will create a target "${PROJECT_NAME}_translations" which will
|
|
# convert the given input po files into the binary output mo file.
|
|
# If the ALL option is used, the translations will also be created
|
|
# when building the default target.
