Per-source copyright/license notice headers that spell out copyright holder names and years are hard to maintain and often out-of-date or plain wrong. Precise contributor information is already maintained automatically by the version control tool. Ultimately it is the receiver of a file who is responsible for determining its licensing status, and per-source notices are merely a convenience. Therefore it is simpler and more accurate for each source to have a generic notice of the license name and references to more detailed information on copyright holders and full license terms. Our `Copyright.txt` file now contains a list of Contributors whose names appeared source-level copyright notices. It also references version control history for more precise information. Therefore we no longer need to spell out the list of Contributors in each source file notice. Replace CMake per-source copyright/license notice headers with a short description of the license and links to `Copyright.txt` and online information available from "https://cmake.org/licensing". The online URL also handles cases of modules being copied out of our source into other projects, so we can drop our notices about replacing links with full license text. Run the `Utilities/Scripts/filter-notices.bash` script to perform the majority of the replacements mechanically. Manually fix up shebang lines and trailing newlines in a few files. Manually update the notices in a few files that the script does not handle.

|
# 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`.
