   2 # Macro CREA_ADVANCED_INSTALL_LIBRARY_FOR_CMAKE
   3 # Creates and install the cmake files which allow
   4 # to find the 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 :

  27 #     ${PROJECT_SOURCE_DIR}/src/part2/include
  28 # * ${LIBRARY_NAME}_BUILD_TREE_RELATIVE_LIBRARY_PATHS

  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 "lib"
  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 # * ${LIBRARY_NAME}_INSTALL_FOLDER : if set then install the generated files
  64 #   in INSTALL_PREFIX/lib/${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 :

  73 #  ${LIBRARY_NAME}_ADDITIONAL_USE_FILE
