Similar to https://gitlab.gnome.org/GNOME/evolution/issues/196 when intltool-merge is called in parallel, it could either rewrite the ongoing attempt to build it or use an incomplete data, which results in broken output files (.desktop, .metainfo and so on). This change ensures the intltool-merge cache is created only once and any other requests which would use it will wait until it's created.

# FindIntltool.cmake

# Searches for intltool and gettext. It aborts, if anything cannot be found.
|
|
# Requires GETTEXT_PO_DIR to be set to full path of the po/ directory.
|
|
#
|
|
# Output is:
|
|
# INTLTOOL_UPDATE - an intltool-update executable path, as found
|
|
# INTLTOOL_EXTRACT - an intltool-extract executable path, as found
|
|
# INTLTOOL_MERGE - an intltool-merge executable path, as found
|
|
#
|
|
# and anything from the FindGettext module.

|
# intltool_add_check_potfiles_target()
|
|
# Adds a check-potfiles target, which verifies that all files with translations
|
|
# are added in the POTFILES.in file inside GETTEXT_PO_DIR. This macro can be called
|
|
# only inside GETTEXT_PO_DIR.
|
|
#
|
|
# intltool_add_pot_file_target()
|
|
# Creates a new target pot-file, which generates ${GETTEXT_PACKAGE}.pot file into
|
|
# the CMAKE_CURERNT_BINARY_DIR. This target is not part of ALL.
|
|
# This can be called only inside GETTEXT_PO_DIR.
|
|
#
|
|
# intltool_process_po_files()
|
|
# Processes all files in the GETTEXT_PO_DIR and generates .gmo files for them
|
|
# in CMAKE_CURRENT_BINARY_DIR. These are added into a new target gmo-files.
|
|
# It also installs them into proper location under LOCALE_INSTALL_DIR.
|
|
# This can be called only inside GETTEXT_PO_DIR.

#
|
|
# intltool_setup_po_dir()
|
|
# Shortcut to setup intltool's po/ directory by adding all custom targets
|
|
# and such. this can be called only inside GETTEXT_PO_DIR.
|
|
#
|
|
# intltool_merge(_in_filename _out_filename ...args)
|
|
# Adds rule to call intltool-merge. The args are optional arguments.
|
|
# This can be called in any folder, only the GETTEXT_PO_DIR should
|
|
# be properly set, otherwise the call will fail.

# A shortcut to call intltool-merge() for an appdata file and install it
