查找Gettext

查找 GNU gettext 工具

该模块寻找 GNU gettext 工具。该模块定义了以下值：

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)

此外，它还提供以下宏：

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 target.
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 target.
It creates a custom target "pofiles".
