ENH: Updated FindImageMagick to:
- Find newer additions such as animate, compare, etc. - Find development api: Magick++, MagickCore, MagickWand - Use FindPackageHandleStandardArgs to output standard messages.

-# - Find Image Magick
-# This module finds if ImageMagick tools are installed and determines
-# where the executables are. This code sets the following variables:
+# - 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):
#
-# IMAGEMAGICK_CONVERT_EXECUTABLE =
-# the full path to the 'convert' utility
-# IMAGEMAGICK_MOGRIFY_EXECUTABLE =
-# the full path to the 'mogrify' utility
-# IMAGEMAGICK_IMPORT_EXECUTABLE =
-# the full path to the 'import' utility
-# IMAGEMAGICK_MONTAGE_EXECUTABLE =
-# the full path to the 'montage' utility
-# IMAGEMAGICK_COMPOSITE_EXECUTABLE =
-# the full path to the 'composite' utility
+# 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.
+#
+# There are also components for the following ImageMagick APIs:
+#
+# Magick++
+# MagickWand
+# Magick
+#
+# 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.).
