# Try to find Libiconv functionality
# Once done this will define
#
# LIBICONV_FOUND - system has Libiconv
# LIBICONV_INCLUDE_DIR - Libiconv include directory
# LIBICONV_LIBRARIES - Libraries needed to use Libiconv
# LIBICONV_SECOND_ARGUMENT_IS_CONST - iconv second argument is const
#
# TODO: This will enable translations only if Gettext functionality is
# present in libc. Must have more robust system for release, where Gettext
# functionality can also reside in standalone Gettext library, or the one
# embedded within kdelibs (cf. gettext.m4 from Gettext source).
