FindIntl
--------

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

The following cache variables may also be set::

Intl_INCLUDE_DIR - the directory containing the libintl headers
  Intl_LIBRARY - the libintl library (if any)

.. 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`.
