# - 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 "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.
