42 | # Initializes the libtiff library. | |
43 | # | |
44 | # libtiff can be configured either to use pre-existing binaries | |
45 | # or to build the library from source. | |
46 | # | |
47 | # Options for configuring a prebuilt libtiff:: | |
48 | # | |
49 | # <search> | |
50 | # The directory containing the libtiff binaries. | |
51 | # <name> | |
52 | # Overrides the default library name. | |
53 | # <include> | |
54 | # The directory containing the libtiff headers. | |
55 | # | |
56 | # If none of these options is specified, then the environmental | |
57 | # variables LIBTIFF_LIBRARY_PATH, LIBTIFF_NAME, and LIBTIFF_INCLUDE will | |
58 | # be used instead. | |
59 | # | |
60 | # Options for building libtiff from source:: | |
61 | # | |
62 | # <source> | |
63 | # The libtiff source directory. Defaults to the environmental variable | |
64 | # LIBTIFF_SOURCE. | |
65 | # <tag> | |
66 | # A rule which computes the actual name of the compiled | |
67 | # libraries based on the build properties. Ignored | |
68 | # when using precompiled binaries. | |
69 | # <build-name> | |
70 | # The base name to use for the compiled library. Ignored | |
71 | # when using precompiled binaries. | |
72 | # | |
73 | # Examples:: | |
74 | # | |
75 | # # Find libtiff in the default system location | |
76 | # using libtiff ; | |
77 | # # Build libtiff from source | |
78 | # using libtiff : 4.0.1 : <source>/home/steven/libtiff-4.0.1 ; | |
79 | # # Find libtiff in /usr/local | |
80 | # using libtiff : 4.0.1 | |
81 | # : <include>/usr/local/include <search>/usr/local/lib ; | |
82 | # # Build libtiff from source for msvc and find | |
83 | # # prebuilt binaries for gcc. | |
84 | # using libtiff : 4.0.1 : <source>C:/Devel/src/libtiff-4.0.1 : <toolset>msvc ; | |
85 | # using libtiff : 4.0.1 : : <toolset>gcc ; | |
