# Gettext support: Create/Update pot file and
#
# To use: INCLUDE(Gettext)
#
# Most of the gettext support code is from FindGettext.cmake of cmake,
# but it is included here because:
#
# 1. Some system like RHEL5 does not have FindGettext.cmake
# 2. Bug of GETTEXT_CREATE_TRANSLATIONS make it unable to be include in 'All'
# 3. It does not support xgettext
#
#===================================================================
# Constants:
#  XGETTEXT_OPTIONS_DEFAULT: Default xgettext option:
#===================================================================
# Variables:
#  XGETTEXT_OPTIONS: Options pass to xgettext
#      Default:  XGETTEXT_OPTIONS_DEFAULT
#  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.
#  XGETTEXT_EXECUTABLE: the full path to the xgettext.
#  XGETTEXT_FOUND: True if xgettext has been found.
#
#===================================================================
# Macros:
# GETTEXT_CREATE_POT(potFile
#    [OPTION xgettext_options]
#    SRC list_of_source_file_that_contains_msgid
# )
#
# Generate .pot file.
#    OPTION xgettext_options: Override XGETTEXT_OPTIONS
#
# * Produced targets: pot_file
#
#-------------------------------------------------------------------
# GETTEXT_CREATE_TRANSLATIONS ( outputFile [ALL] locale1 ... localeN
#     [COMMENT comment] )
#
#     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.
#
# * Produced targets: translations
