  45 # Initializes the libjpeg library.
  46 #
  47 # libjpeg can be configured either to use pre-existing binaries
  48 # or to build the library from source.
  49 #
  50 # Options for configuring a prebuilt libjpeg::
  51 #
  52 #   <search>
  53 #       The directory containing the libjpeg binaries.
  54 #   <name>
  55 #       Overrides the default library name.
  56 #   <include>
  57 #       The directory containing the libjpeg headers.
  58 #
  59 # If none of these options is specified, then the environmental
  60 # variables LIBJPEG_LIBRARY_PATH, LIBJPEG_NAME, and LIBJPEG_INCLUDE will
  61 # be used instead.
  62 #
  63 # Options for building libjpeg from source::
  64 #
  65 #   <source>
  66 #       The libjpeg source directory.  Defaults to the environmental variable
  67 #       LIBJPEG_SOURCE.
  68 #   <tag>
  69 #       A rule which computes the actual name of the compiled
  70 #       libraries based on the build properties.  Ignored
  71 #       when using precompiled binaries.
  72 #   <build-name>
  73 #       The base name to use for the compiled library.  Ignored
  74 #       when using precompiled binaries.
  75 #
  76 # Examples::
  77 #
  78 #   # Find libjpeg in the default system location
  79 #   using libjpeg ;
  80 #   # Build libjpeg from source
  81 #   using libjpeg : 8c : <source>/home/steven/libjpeg-8c ;
  82 #   # Find libjpeg in /usr/local
  83 #   using libjpeg : 8c
  84 #     : <include>/usr/local/include <search>/usr/local/lib ;
  85 #   # Build libjpeg from source for msvc and find
  86 #   # prebuilt binaries for gcc.
  87 #   using libjpeg : 8c : <source>C:/Devel/src/libjpeg-8c : <toolset>msvc ;
