# Locate ImageMagick configuration program
# ImageMagick has the config program:
# bin/Wand-config
# bin/MagickWand-config
#
# Sets
#  IM_WAND_BINARY
#  IM_IMAGEMAGICK_PREFIX
#  IM_IMAGEMAGICK_VERSION
#  IM_IMAGEMAGICK_VERSION_MASK
#  IM_USE_PKG_CONFIG
#
# Usage:
#   IM_FIND_IMAGEMAGICK (MINIMUM_VERSION, EXTRA_SEARCH_PREFIX)
#
# Note:
# IM_PREFIX - the directory reported by `MagickWand-config --prefix`
# IM_IMAGEMAGICK_PREFIX - the user specified location to use
