1 # - Find the ImageMagick binary suite. 2 # This module will search for a set of ImageMagick tools specified 3 # as components in the FIND_PACKAGE call. Typical components include, 4 # but are not limited to (future versions of ImageMagick might have 5 # additional components not listed here): 6 # 7 # animate 8 # compare 9 # composite 10 # conjure 11 # convert 12 # display 13 # identify 14 # import 15 # mogrify 16 # montage 17 # stream 18 # 19 # If no component is specified in the FIND_PACKAGE call, then it only 20 # searches for the ImageMagick executable directory. This code defines 21 # the following variables: 22 # 23 # ImageMagick_FOUND - TRUE if all components are found. 24 # ImageMagick_EXECUTABLE_DIR - Full path to executables directory. 25 # ImageMagick_<component>_FOUND - TRUE if <component> is found. 26 # ImageMagick_<component>_EXECUTABLE - Full path to <component> executable. 27 # 28 # There are also components for the following ImageMagick APIs: 29 # 30 # Magick++ 31 # MagickWand 32 # MagickCore 33 # 34 # For these components the following variables are set: 35 # 36 # ImageMagick_FOUND - TRUE if all components are found. 37 # ImageMagick_INCLUDE_DIRS - Full paths to all include dirs. 38 # ImageMagick_LIBRARIES - Full paths to all libraries. 39 # ImageMagick_<component>_FOUND - TRUE if <component> is found. 40 # ImageMagick_<component>_INCLUDE_DIRS - Full path to <component> include dirs. 41 # ImageMagick_<component>_LIBRARIES - Full path to <component> libraries. 42 # 43 # Example Usages: 44 # FIND_PACKAGE(ImageMagick) 45 # FIND_PACKAGE(ImageMagick COMPONENTS convert) 46 # FIND_PACKAGE(ImageMagick COMPONENTS convert mogrify display) 47 # FIND_PACKAGE(ImageMagick COMPONENTS Magick++) 48 # FIND_PACKAGE(ImageMagick COMPONENTS Magick++ convert) 49 # 50 # Note that the standard FIND_PACKAGE features are supported 51 # (i.e., QUIET, REQUIRED, etc.). 52 53 #============================================================================= 54 # Copyright 2007-2009 Kitware, Inc. 55 # Copyright 2007-2008 Miguel A.
