Add support for Sun/Uniforum/GNU gettext libintl. This belongs in CMake rather than upstream because: * There are multiple upstreams (Sun, GNU). * It may or may not be in the glibc C library depending upon the platform and build options used. Although we already have a FindGettext module, that is for the tools. This module is for the library, and is independent because it's perfectly OK to use libintl without the gettext tools (and vice versa), and they might not all be found. Add cross references between the two modules in notes to make the relationship clearer.

# 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`.
