-# - Functions to help assemble a standalone bundle application.
-# A collection of CMake utility functions useful for dealing with .app
-# bundles on the Mac and bundle-like directories on any OS.

-#   fixup_bundle
-#   copy_and_fixup_bundle
-#   verify_app
-#   get_bundle_main_executable
-#   get_dotapp_dir
-#   get_bundle_and_executable

-#   copy_resolved_framework_into_bundle
-#   fixup_bundle_item
-#   verify_bundle_prerequisites
-#   verify_bundle_symlinks
-# Requires CMake 2.6 or greater because it uses function, break and
-# PARENT_SCOPE. Also depends on GetPrerequisites.cmake.
-#
-#  FIXUP_BUNDLE(<app> <libs> <dirs>)
-# Fix up a bundle in-place and make it standalone, such that it can be
-# drag-n-drop copied to another machine and run on that machine as long as all
-# of the system libraries are compatible.
-#
-# If you pass plugins to fixup_bundle as the libs parameter, you should install
-# them or copy them into the bundle before calling fixup_bundle. The "libs"
-# parameter is a list of libraries that must be fixed up, but that cannot be
-# determined by otool output analysis. (i.e., plugins)
-#
-# Gather all the keys for all the executables and libraries in a bundle, and
-# then, for each key, copy each prerequisite into the bundle. Then fix each one
-# up according to its own list of prerequisites.
-#
-# Then clear all the keys and call verify_app on the final bundle to ensure
-# that it is truly standalone.
-#
-#  COPY_AND_FIXUP_BUNDLE(<src> <dst> <libs> <dirs>)
-# Makes a copy of the bundle <src> at location <dst> and then fixes up the
-# new copied bundle in-place at <dst>...
-#
-#  VERIFY_APP(<app>)
-# Verifies that an application <app> appears valid based on running analysis
-# tools on it. Calls "message(FATAL_ERROR" if the application is not verified.
-#
-#  GET_BUNDLE_MAIN_EXECUTABLE(<bundle> <result_var>)
-# The result will be the full path name of the bundle's main executable file
-# or an "error:" prefixed string if it could not be determined.
-#
-#  GET_DOTAPP_DIR(<exe> <dotapp_dir_var>)
-# Returns the nearest parent dir whose name ends with ".app" given the full
-# path to an executable. If there is no such parent dir, then simply return
-# the dir containing the executable.
-#
-# The returned directory may or may not exist.
-#
-#  GET_BUNDLE_AND_EXECUTABLE(<app> <bundle_var> <executable_var> <valid_var>)
-# Takes either a ".app" directory name or the name of an executable
-# nested inside a ".app" directory and returns the path to the ".app"
-# directory in <bundle_var> and the path to its main executable in
-# <executable_var>
-#
-#  GET_BUNDLE_ALL_EXECUTABLES(<bundle> <exes_var>)
-# Scans the given bundle recursively for all executable files and accumulates
-# them into a variable.
-#
-#  GET_ITEM_KEY(<item> <key_var>)
-# Given a file (item) name, generate a key that should be unique considering
-# the set of libraries that need copying or fixing up to make a bundle
-# standalone. This is essentially the file name including extension with "."
-# replaced by "_"
-#
-# This key is used as a prefix for CMake variables so that we can associate a
-# set of variables with a given item based on its key.
-#
-#  CLEAR_BUNDLE_KEYS(<keys_var>)
-# Loop over the list of keys, clearing all the variables associated with each
-# key. After the loop, clear the list of keys itself.
-#
-# Caller of get_bundle_keys should call clear_bundle_keys when done with list
-# of keys.
-#
-#  SET_BUNDLE_KEY_VALUES(<keys_var> <context> <item> <exepath> <dirs>
-#                        <copyflag>)
-# Add a key to the list (if necessary) for the given item. If added,
-# also set all the variables associated with that key.
-#
-#  GET_BUNDLE_KEYS(<app> <libs> <dirs> <keys_var>)
-# Loop over all the executable and library files within the bundle (and given
-# as extra <libs>) and accumulate a list of keys representing them. Set
-# values associated with each key such that we can loop over all of them and
-# copy prerequisite libs into the bundle and then do appropriate
-# install_name_tool fixups.
-#
-#  COPY_RESOLVED_ITEM_INTO_BUNDLE(<resolved_item> <resolved_embedded_item>)
-# Copy a resolved item into the bundle if necessary. Copy is not necessary if
-# the resolved_item is "the same as" the resolved_embedded_item.
-#
-#  COPY_RESOLVED_FRAMEWORK_INTO_BUNDLE(<resolved_item> <resolved_embedded_item>)
-# Copy a resolved framework into the bundle if necessary. Copy is not necessary
-# if the resolved_item is "the same as" the resolved_embedded_item.
-#
-# By default, BU_COPY_FULL_FRAMEWORK_CONTENTS is not set. If you want full
-# frameworks embedded in your bundles, set BU_COPY_FULL_FRAMEWORK_CONTENTS to
-# ON before calling fixup_bundle. By default,
-# COPY_RESOLVED_FRAMEWORK_INTO_BUNDLE copies the framework dylib itself plus
-# the framework Resources directory.
-#
-#  FIXUP_BUNDLE_ITEM(<resolved_embedded_item> <exepath> <dirs>)
-# Get the direct/non-system prerequisites of the resolved embedded item. For
-# each prerequisite, change the way it is referenced to the value of the
-# _EMBEDDED_ITEM keyed variable for that prerequisite. (Most likely changing to
-# an "@executable_path" style reference.)
-#
-# This function requires that the resolved_embedded_item be "inside" the bundle
-# already. In other words, if you pass plugins to fixup_bundle as the libs
-# parameter, you should install them or copy them into the bundle before
-# calling fixup_bundle. The "libs" parameter is a list of libraries that must
-# be fixed up, but that cannot be determined by otool output analysis. (i.e.,
-# plugins)
-#
-# Also, change the id of the item being fixed up to its own _EMBEDDED_ITEM
-# value.
-#
-# Accumulate changes in a local variable and make *one* call to
-# install_name_tool at the end of the function with all the changes at once.
-#
-# If the BU_CHMOD_BUNDLE_ITEMS variable is set then bundle items will be
-# marked writable before install_name_tool tries to change them.
-#
-#  VERIFY_BUNDLE_PREREQUISITES(<bundle> <result_var> <info_var>)
-# Verifies that the sum of all prerequisites of all files inside the bundle
-# are contained within the bundle or are "system" libraries, presumed to exist
-# everywhere.
-#
-#  VERIFY_BUNDLE_SYMLINKS(<bundle> <result_var> <info_var>)
-# Verifies that any symlinks found in the bundle point to other files that are
-# already also in the bundle... Anything that points to an external file causes
-# this function to fail the verification.

-# Print the prerequisites of shared library and executable files matching a

-# globbing expression used with "file(GLOB" or "file(GLOB_RECURSE" to retrieve
-# a list of matching files. If a matching file is executable, its prerequisites
-# are listed.

-# If only resource files are given then just a jar file is created.
-#
-# Additional instructions:
-#   To add compile flags to the target you can set these flags with
-#   the following variable:
-#
-#       set(CMAKE_JAVA_COMPILE_FLAGS -nowarn)
-#
-#   To add a path or a jar file to the class path you can do this

-#
-#   To define an entry point in your jar you can set it with:
-#
-#       set(CMAKE_JAVA_JAR_ENTRY_POINT com/examples/MyProject/Main)
-#
-#   To add a VERSION to the target output name you can set it using
-#   CMAKE_JAVA_TARGET_VERSION. This will create a jar file with the name
-#   shibboleet-1.0.0.jar and will create a symlink shibboleet.jar
-#   pointing to the jar with the version information.

-#       install_jni_symlink(shibboleet ${JAVA_LIB_INSTALL_DIR})
-#
-#    If a single target needs to produce more than one jar from its
-#    java source code, to prevent the accumulation of duplicate class

-#
-# There are two main signatures for create_javadoc. The first
-# signature works with package names on a path with source files:
-#
-#   Example:
-#   create_javadoc(my_example_doc
-#     PACKAGES com.exmaple.foo com.example.bar
-#     SOURCEPATH "${CMAKE_CURRENT_SOURCE_DIR}"
-#     CLASSPATH ${CMAKE_JAVA_INCLUDE_PATH}
-#     WINDOWTITLE "My example"
-#     DOCTITLE "<h1>My example</h1>"
-#     AUTHOR TRUE
-#     USE TRUE
-#     VERSION TRUE
-#   )
-#
-# The second signature for create_javadoc works on a given list of
-# files.
-#
-#   create_javadoc(<VAR>
-#                  FILES file1 [file2 ...]
-#                  [CLASSPATH <classpath>]
-#                  [INSTALLPATH <install path>]
-#                  [DOCTITLE "the documentation title"]
-#                  [WINDOWTITLE "the title of the document"]
-#                  [AUTHOR TRUE|FALSE]
-#                  [USE TRUE|FALSE]
-#                  [VERSION TRUE|FALSE]
-#                 )
-#
-# Example:
-#   create_javadoc(my_example_doc
-#     FILES ${example_SRCS}
-#     CLASSPATH ${CMAKE_JAVA_INCLUDE_PATH}
-#     WINDOWTITLE "My example"
-#     DOCTITLE "<h1>My example</h1>"
-#     AUTHOR TRUE
-#     USE TRUE
-#     VERSION TRUE
-#   )
-#
-# Both signatures share most of the options. These options are the
-# same as what you can find in the javadoc manpage. Please look at
-# the manpage for CLASSPATH, DOCTITLE, WINDOWTITLE, AUTHOR, USE and
-# VERSION.
-#
-# The documentation will be by default installed to
-#
-#   ${CMAKE_INSTALL_PREFIX}/share/javadoc/<VAR>
-#
-# if you don't set the INSTALLPATH.
