# - 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.
#
# Example Usages:
#  FIND_PACKAGE(ImageMagick)
#  FIND_PACKAGE(ImageMagick COMPONENTS latex dvips ps2pdf bibtex)
#  FIND_PACKAGE(ImageMagick COMPONENTS pdflatex bibtex)
#
# Note that the standard FIND_PACKAGE features are supported
# (i.e., QUIET, REQUIRED, etc.).
