1 # FindIntltool.cmake 2 # 3 # Searches for intltool and gettext. It aborts, if anything cannot be found. 4 # Requires GETTEXT_PO_DIR to be set to full path of the po/ directory. 5 # 6 # Output is: 7 # INTLTOOL_UPDATE - an intltool-update executable path, as found 8 # INTLTOOL_EXTRACT - an intltool-extract executable path, as found 9 # INTLTOOL_MERGE - an intltool-merge executable path, as found 10 # 11 # and anything from the FindGettext module. 12 # 13 # The below provided macros require GETTEXT_PACKAGE to be set. 14 # 15 # intltool_add_check_potfiles_target() 16 # Adds a check-potfiles target, which verifies that all files with translations 17 # are added in the POTFILES.in file inside GETTEXT_PO_DIR. This macro can be called 18 # only inside GETTEXT_PO_DIR. 19 # 20 # intltool_add_pot_file_target() 21 # Creates a new target pot-file, which generates ${GETTEXT_PACKAGE}.pot file into 22 # the CMAKE_CURERNT_BINARY_DIR. This target is not part of ALL. 23 # This can be called only inside GETTEXT_PO_DIR. 24 # 25 # intltool_process_po_files() 26 # Processes all files in the GETTEXT_PO_DIR and generates .gmo files for them 27 # in CMAKE_CURRENT_BINARY_DIR. These are added into a new target gmo-files. 28 # It also installs them into proper location under LOCALE_INSTALL_DIR. 29 # This can be called only inside GETTEXT_PO_DIR. 30 # 31 # intltool_setup_po_dir() 32 # Shortcut to setup intltool's po/ directory by adding all custom targets 33 # and such. this can be called only inside GETTEXT_PO_DIR. 34 # 35 # intltool_merge(_in_filename _out_filename ...args) 36 # Adds rule to call intltool-merge.
