# 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".
