# - Try to find Iconv
# Once done this will define

# ICONV_FOUND - system has Iconv
# ICONV_INCLUDE_DIR - the Iconv include directory
# ICONV_LIBRARIES - Link these to use Iconv
# ICONV_IS_CONST - the second argument for iconv() is const
#
# This was mostly borrowed from Strigi. LyX also has a (quite
# different) FindICONV: the one in LyX does not check
# second_argument_is_const, but seems to have more fleshed-out support
# for WIN32. There may need to be some merging done.
