FindIntl
|
|
--------
|
|
|
|
.. versionadded:: 3.2
|
|
|
|
Find the Gettext libintl headers and libraries.
|
|
|
|
This module reports information about the Gettext libintl
|
|
installation in several variables. General variables::
|
|
|
|
Intl_FOUND - true if the libintl headers and libraries were found
|
|
Intl_INCLUDE_DIRS - the directory containing the libintl headers
|
|
Intl_LIBRARIES - libintl libraries to be linked
|
|
|
|
.. versionadded:: 3.20
|
|
This module defines :prop_tgt:`IMPORTED` target ``Intl::Intl``.
|
|
|
|
The following cache variables may also be set::
|
|
|
|
Intl_INCLUDE_DIR - the directory containing the libintl headers
|
|
Intl_LIBRARY - the libintl library (if any)
|
|
Intl_HAVE_GETTEXT_BUILTIN - check if gettext is in the C library
|
|
Intl_HAVE_DCGETTEXT_BUILTIN - check if dcgettext is in the C library
|
|
Intl_IS_BUILTIN - whether intl is a part of the C library determined
|
|
from the result of Intl_HAVE_GETTEXT_BUILTIN and Intl_HAVE_DCGETTEXT_BUILTIN
|
|
|
|
.. versionadded:: 3.20
|
|
Added the ``Intl_HAVE_GETTEXT_BUILTIN``, ``Intl_HAVE_DCGETTEXT_BUILTIN`` and
|
|
``Intl_IS_BUILTIN`` variables.
|
|
|
|
.. note::
|
|
On some platforms, such as Linux with GNU libc, the gettext
|
|
functions are present in the C standard library and libintl
|
|
is not required. ``Intl_LIBRARIES`` will be empty in this
|
|
case.
|
|
|
|
.. note::
|
|
If you wish to use the Gettext tools (``msgmerge``,
|
|
``msgfmt``, etc.), use :module:`FindGettext`.
