The functions in FindGettext create a custom target. If the functions are called multiple times, multiple times the same target is created. This works only if CMP0002 is set to OLD. With this patch there is only one central target created, and each invocation of the function creates a target with a unique name and make the central target depend on this one. Alex

# - 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".
