# 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_FILE( <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".
|
|
#
|
|
# .. note::
|
|
# If you wish to use the Gettext library (libintl), use :module:`FindIntl`.
