# 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.).
