2 # Macro CREA_ADVANCED_INSTALL_LIBRARY
3 # Creates and install the cmake files which allow 
4 # to find a library by the cmake command FIND_PACKAGE.
5 #
6 # Inputs :
7 # --------
8 #  LIBRARY_NAME : name of the library to find 
9 #
10 # The following variables **MUST** have been set previously :
11 #
12 # * ${LIBRARY_NAME}_BUILD_TREE_RELATIVE_INCLUDE_PATHS
13 #    The list of include paths 
14 #    when someone uses a *BUILD TREE* version of ${LIBRARY_NAME}.
15 #    NB : 
16 #     THE PATHS *MUST BE RELATIVE* TO THE ROOT DIR OF THE PROJECT **SOURCES** !
17 #    Assume your project architecture is :
18 #     install/ : directory in which the macro is invoked
19 #     src/part1/include/ : first include dir
20 #     src/part2/include/ : second include dir
21 #    Then you should set the var with :
22 #    SET(${LIBRARY_NAME}_BUILD_TREE_RELATIVE_INCLUDE_PATHS
23 #     src/part1/include
24 #     src/part2/include )
25 #    Which will result in actual include paths :
26 #     ${PROJECT_SOURCE_DIR}/src/part1/include;
27 #     ${PROJECT_SOURCE_DIR}/src/part2/include
28 # * ${LIBRARY_NAME}_BUILD_TREE_RELATIVE_LIBRARY_PATHS
29 #    Like the previous var but for the library paths.
30 #    NB : 
31 #     THE PATHS *MUST BE RELATIVE* TO THE ROOT DIR OF THE **BUILD TREE** 
32 #     THAT IS POINT TO THE FOLDERS WHERE THE LIBS WILL BE BUILD
33 #    Assume that your project architecture is :
34 #     src/part1/src/ : first source dir, in which the lib 'part1' is built
35 #     src/part2/src/ : first source dir, in which the lib 'part2' is built
36 #    Then you should set the var with 
37 #    SET(${LIBRARY_NAME}_BUILD_TREE_RELATIVE_LIBRARY_PATHS
38 #     src/part1/src
39 #     src/part2/src
40 #     )
41 #    Which will result in actual library paths :
42 #     ${PROJECT_BINARY_DIR}/src/part1/src
43 #     ${PROJECT_BINARY_DIR}/src/part2/src
44 # * ${LIBRARY_NAME}_INSTALL_TREE_RELATIVE_INCLUDE_PATHS
45 #    The list of include paths 
46 #    when someone uses an *INSTALLED* version of ${LIBRARY_NAME} 
47 #    The paths *MUST BE RELATIVE* to INSTALL_PREFIX
48 #  #    A typical example is "include/${LIBRARY_NAME}"
49 # * ${LIBRARY_NAME}_INSTALL_TREE_RELATIVE_LIBRARY_PATHS
50 #    Like the previous var but for library paths.
51 #    A typical example is ".."
52 # * ${LIBRARY_NAME}_LIBRARIES
53 #    The list of libraries to link against when using ${LIBRARY_NAME}
54 #
55 # The following variables can be set optionally :
56 #
57 # * ${LIBRARY_NAME}_REQUIRED_C_FLAGS
58 # * ${LIBRARY_NAME}_REQUIRED_CXX_FLAGS
59 # * ${LIBRARY_NAME}_REQUIRED_LINK_FLAGS
60 # * ${LIBRARY_NAME}_MAJOR_VERSION
61 # * ${LIBRARY_NAME}_MINOR_VERSION
62 # * ${LIBRARY_NAME}_BUILD_VERSION
63 # * ${LIBRARY_NAME}_INSTALL_FOLDER : if set then install the stuff 
64 #   in INSTALL_PREFIX/lib/${LIBRARY_NAME}_INSTALL_FOLDER 
65 #   instead of INSTALL_PREFIX/lib/${LIBRARY_NAME}
66 #
67
68 # To provide a user defined 
69 # couple of Config/Use file (in addition to the standard one) use :
70 #  SET( ${LIBRARY_NAME}_HAS_ADDITIONAL_CONFIG_FILE  TRUE )
71 # and store the *ABSOLUTE* paths to the additional files in the vars :
72 #  ${LIBRARY_NAME}_ADDITIONAL_CONFIG_FILE
73 #  ${LIBRARY_NAME}_ADDITIONAL_USE_FILE
74 # (e.g. ${CMAKE_CURRENT_SOURCE_DIR}/MyConfig.cmake)
75 #
76 # Outputs :
77 # --------
78 # At cmake run-time, the macro creates the following files 
79 # in the current dir of the build tree (where the macro is invoked) :
80 #  Use${LIBRARY_NAME}.cmake
81 #  ${LIBRARY_NAME}Config.cmake
82 #  ${LIBRARY_NAME}BuildSettings.cmake
83 # And if the vars ${LIBRARY_NAME}_ADDITIONAL_CONFIG_FILE and
84 # ${LIBRARY_NAME}_ADDITIONAL_USE_FILE are set, it also creates :
85 #  Additional${LIBRARY_NAME}Config.cmake
86 #  AdditionalUse${LIBRARY_NAME}.cmake
87
88 # At install-time, the same files are installed 
89 # in INSTALL_PREFIX/lib/${LIBRARY_NAME}
90 # and the file :
91 #  Find${LIBRARY_NAME}.cmake
92 # is installed in ${CMAKE_ROOT}/Modules/
