#.rst:
# FindImageMagick
# ---------------
#
# Find the ImageMagick binary suite.
#
# This module will search for a set of ImageMagick tools specified as
# components in the FIND_PACKAGE call. Typical components include, but
# are not limited to (future versions of ImageMagick might have
# additional components not listed here):
#
# ::
#
# animate
# compare
# composite
# conjure
# convert
# display
# identify
# import
# mogrify
# montage
# stream
#
#
#
# If no component is specified in the FIND_PACKAGE call, then it only
# searches for the ImageMagick executable directory. This code defines
# the following variables:
#
# ::
#
# ImageMagick_FOUND - TRUE if all components are found.
# ImageMagick_EXECUTABLE_DIR - Full path to executables directory.
# ImageMagick_<component>_FOUND - TRUE if <component> is found.
# ImageMagick_<component>_EXECUTABLE - Full path to <component> executable.
# ImageMagick_VERSION_STRING - the version of ImageMagick found
# (since CMake 2.8.8)
#
#
#
# ImageMagick_VERSION_STRING will not work for old versions like 5.2.3.
#
# There are also components for the following ImageMagick APIs:
#
# ::
#
# Magick++
# MagickWand
# MagickCore
#
#
#
# For these components the following variables are set:
#
# ::
#
# ImageMagick_FOUND - TRUE if all components are found.
# ImageMagick_INCLUDE_DIRS - Full paths to all include dirs.
# ImageMagick_LIBRARIES - Full paths to all libraries.
# ImageMagick_<component>_FOUND - TRUE if <component> is found.
# ImageMagick_<component>_INCLUDE_DIRS - Full path to <component> include dirs.
# ImageMagick_<component>_LIBRARIES - Full path to <component> libraries.
#
#
#
# Example Usages:
#
# ::
#
# find_package(ImageMagick)
# find_package(ImageMagick COMPONENTS convert)
# find_package(ImageMagick COMPONENTS convert mogrify display)
# find_package(ImageMagick COMPONENTS Magick++)
# find_package(ImageMagick COMPONENTS Magick++ convert)
#
#
#
# Note that the standard FIND_PACKAGE features are supported (i.e.,
# QUIET, REQUIRED, etc.).
