  48 # Initializes the libjpeg library.
  49 #
  50 # libjpeg can be configured either to use pre-existing binaries
  51 # or to build the library from source.
  52 #
  53 # Options for configuring a prebuilt libjpeg::
  54 #
  55 #   <search>
  56 #       The directory containing the libjpeg binaries.
  57 #   <name>
  58 #       Overrides the default library name.
  59 #   <include>
  60 #       The directory containing the libjpeg headers.
  61 #
  62 # If none of these options is specified, then the environmental
  63 # variables LIBJPEG_LIBRARY_PATH, LIBJPEG_NAME, and LIBJPEG_INCLUDE will
  64 # be used instead.
  65 #
  66 # Options for building libjpeg from source::
  67 #
  68 #   <source>
  69 #       The libjpeg source directory.  Defaults to the environmental variable
  70 #       LIBJPEG_SOURCE.
  71 #   <tag>
  72 #       A rule which computes the actual name of the compiled
  73 #       libraries based on the build properties.  Ignored
  74 #       when using precompiled binaries.
  75 #   <build-name>
  76 #       The base name to use for the compiled library.  Ignored
  77 #       when using precompiled binaries.
  78 #
  79 # Examples::
  80 #
  81 #   # Find libjpeg in the default system location
  82 #   using libjpeg ;
  83 #   # Build libjpeg from source
  84 #   using libjpeg : 8c : <source>/home/steven/libjpeg-8c ;
  85 #   # Find libjpeg in /usr/local
  86 #   using libjpeg : 8c
  87 #     : <include>/usr/local/include <search>/usr/local/lib ;
  88 #   # Build libjpeg from source for msvc and find
  89 #   # prebuilt binaries for gcc.
  90 #   using libjpeg : 8c : <source>C:/Devel/src/libjpeg-8c : <toolset>msvc ;
  91 #   using libjpeg : 8c : : <toolset>gcc ;
