# - 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.
# GETTEXT_VERSION_STRING: the version of gettext found (since CMake 2.8.8)
#
# 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.
# GETTEXT_PROCESS_POT( <potfile> [ALL] [INSTALL_DESTINATION <destdir>] LANGUAGES <lang1> <lang2> ... )
# Process the given pot file to mo files.
# If INSTALL_DESTINATION is given then automatically install rules will be created,
# the language subdirectory will be taken into account (by default use share/locale/).
# If ALL is specified, the pot file is processed when building the all traget.
# It creates a custom target "potfile".
# GETTEXT_PROCESS_PO_FILES( <lang> [ALL] [INSTALL_DESTINATION <dir>] PO_FILES <po1> <po2> ... )
# Process the given po files to mo files for the given language.
# If INSTALL_DESTINATION is given then automatically install rules will be created,
# the language subdirectory will be taken into account (by default use share/locale/).
# If ALL is specified, the po files are processed when building the all traget.
# It creates a custom target "pofiles".
