-# - 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.
-#
-# The following functions are provided by this module:
-#   fixup_bundle
-#   copy_and_fixup_bundle
-#   verify_app
-#   get_bundle_main_executable
-#   get_dotapp_dir
-#   get_bundle_and_executable
-#   get_bundle_all_executables
-#   get_item_key
-#   clear_bundle_keys
-#   set_bundle_key_values
-#   get_bundle_keys
-#   copy_resolved_item_into_bundle
-#   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.

-# - Functions to analyze and list executable file prerequisites.
-# This module provides functions to list the .dll, .dylib or .so
-# files that an executable or shared library file depends on. (Its
-# prerequisites.)
-#
-# It uses various tools to obtain the list of required shared library files:
-#   dumpbin (Windows)
-#   objdump (MinGW on Windows)
-#   ldd (Linux/Unix)
-#   otool (Mac OSX)
-# The following functions are provided by this module:
-#   get_prerequisites
-#   list_prerequisites
-#   list_prerequisites_by_glob
-#   gp_append_unique
-#   is_file_executable
-#   gp_item_default_embedded_path
-#     (projects can override with gp_item_default_embedded_path_override)
-#   gp_resolve_item
-#     (projects can override with gp_resolve_item_override)
-#   gp_resolved_file_type
-#     (projects can override with gp_resolved_file_type_override)
-#   gp_file_type
-# Requires CMake 2.6 or greater because it uses function, break, return and
-# PARENT_SCOPE.
-#
-#  GET_PREREQUISITES(<target> <prerequisites_var> <exclude_system> <recurse>
-#                    <exepath> <dirs>)
-# Get the list of shared library files required by <target>. The list in
-# the variable named <prerequisites_var> should be empty on first entry to
-# this function. On exit, <prerequisites_var> will contain the list of
-# required shared library files.
-#
-# <target> is the full path to an executable file. <prerequisites_var> is the
-# name of a CMake variable to contain the results. <exclude_system> must be 0
-# or 1 indicating whether to include or exclude "system" prerequisites. If
-# <recurse> is set to 1 all prerequisites will be found recursively, if set to
-# 0 only direct prerequisites are listed. <exepath> is the path to the top
-# level executable used for @executable_path replacment on the Mac. <dirs> is
-# a list of paths where libraries might be found: these paths are searched
-# first when a target without any path info is given. Then standard system
-# locations are also searched: PATH, Framework locations, /usr/lib...
-#
-#  LIST_PREREQUISITES(<target> [<recurse> [<exclude_system> [<verbose>]]])
-# Print a message listing the prerequisites of <target>.
-#
-# <target> is the name of a shared library or executable target or the full
-# path to a shared library or executable file. If <recurse> is set to 1 all
-# prerequisites will be found recursively, if set to 0 only direct
-# prerequisites are listed. <exclude_system> must be 0 or 1 indicating whether
-# to include or exclude "system" prerequisites. With <verbose> set to 0 only
-# the full path names of the prerequisites are printed, set to 1 extra
-# informatin will be displayed.
-#
-#  LIST_PREREQUISITES_BY_GLOB(<glob_arg> <glob_exp>)
-# Print the prerequisites of shared library and executable files matching a
-# globbing pattern. <glob_arg> is GLOB or GLOB_RECURSE and <glob_exp> is 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.
-#
-# Any additional (optional) arguments provided are passed along as the
-# optional arguments to the list_prerequisites calls.
-#
-#  GP_APPEND_UNIQUE(<list_var> <value>)
-# Append <value> to the list variable <list_var> only if the value is not
-# already in the list.
-#
-#  IS_FILE_EXECUTABLE(<file> <result_var>)
-# Return 1 in <result_var> if <file> is a binary executable, 0 otherwise.
-#
-#  GP_ITEM_DEFAULT_EMBEDDED_PATH(<item> <default_embedded_path_var>)
-# Return the path that others should refer to the item by when the item
-# is embedded inside a bundle.
-#
-# Override on a per-project basis by providing a project-specific
-# gp_item_default_embedded_path_override function.
-#
-#  GP_RESOLVE_ITEM(<context> <item> <exepath> <dirs> <resolved_item_var>)
-# Resolve an item into an existing full path file.
-#
-# Override on a per-project basis by providing a project-specific
-# gp_resolve_item_override function.
-#
-#  GP_RESOLVED_FILE_TYPE(<original_file> <file> <exepath> <dirs> <type_var>)
-# Return the type of <file> with respect to <original_file>. String
-# describing type of prerequisite is returned in variable named <type_var>.
-#
-# Use <exepath> and <dirs> if necessary to resolve non-absolute <file>
-# values -- but only for non-embedded items.
-#
-# Possible types are:
-#   system
-#   local
-#   embedded
-#   other
-# Override on a per-project basis by providing a project-specific
-# gp_resolved_file_type_override function.
-#
-#  GP_FILE_TYPE(<original_file> <file> <type_var>)
-# Return the type of <file> with respect to <original_file>. String

-# has already been loaded.  See FindJava.cmake for information on how to
-# load Java into your CMake project.
-#
-# add_jar(TARGET_NAME SRC1 SRC2 .. SRCN RCS1 RCS2 .. RCSN)
-#
-# This command creates a <TARGET_NAME>.jar. It compiles the given source
-# files (SRC) and adds the given resource files (RCS) to the jar file.
-# 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
-#   with the CMAKE_JAVA_INCLUDE_PATH variable.
-#
-#       set(CMAKE_JAVA_INCLUDE_PATH /usr/share/java/shibboleet.jar)
-#
-#   To use a different output name for the target you can set it with:
-#
-#       set(CMAKE_JAVA_TARGET_OUTPUT_NAME shibboleet.jar)
-#       add_jar(foobar foobar.java)
-#
-#   To use a different output directory than CMAKE_CURRENT_BINARY_DIR
-#   you can set it with:
-#
-#       set(CMAKE_JAVA_TARGET_OUTPUT_DIR ${PROJECT_BINARY_DIR}/bin)
-#
-#   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.
-#
-#       set(CMAKE_JAVA_TARGET_VERSION 1.2.0)
-#       add_jar(shibboleet shibbotleet.java)
-#
-#    If the target is a JNI library, utilize the following commands to
-#    create a JNI symbolic link:
-#
-#       set(CMAKE_JNI_TARGET TRUE)
-#       set(CMAKE_JAVA_TARGET_VERSION 1.2.0)
-#       add_jar(shibboleet shibbotleet.java)
-#       install_jar(shibboleet ${LIB_INSTALL_DIR}/shibboleet)
-#       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
-#    files in subsequent jars, set/reset CMAKE_JAR_CLASSES_PREFIX prior
-#    to calling the add_jar() function:
-#
-#       set(CMAKE_JAR_CLASSES_PREFIX com/redhat/foo)
-#       add_jar(foo foo.java)
-#
-#       set(CMAKE_JAR_CLASSES_PREFIX com/redhat/bar)
-#       add_jar(bar bar.java)
-#
-# Target Properties:
-#   The add_jar() functions sets some target properties. You can get these
-#   properties with the
-#      get_property(TARGET <target_name> PROPERTY <propery_name>)
-#   command.
-#
-#   INSTALL_FILES      The files which should be installed. This is used by
-#                      install_jar().
-#   JNI_SYMLINK        The JNI symlink which should be installed.
-#                      This is used by install_jni_symlink().
-#   JAR_FILE           The location of the jar file so that you can include
-#                      it.
-#   CLASS_DIR          The directory where the class files can be found. For
-#                      example to use them with javah.
-#

-#          [DOC "cache documentation string"]
-#         )
-#
-# This command is used to find a full path to the named jar. A cache
-# entry named by <VAR> is created to stor the result of this command. If
-# the full path to a jar is found the result is stored in the variable
-# and the search will not repeated unless the variable is cleared. If
-# nothing is found, the result will be <VAR>-NOTFOUND, and the search
-# will be attempted again next time find_jar is invoked with the same
-# variable.
-# The name of the full path to a file that is searched for is specified
-# by the names listed after NAMES argument. Additional search locations
-# can be specified after the PATHS argument. If you require special a
-# version of a jar file you can specify it with the VERSIONS argument.
-# The argument after DOC will be used for the documentation string in
-# the cache.

-# Create java documentation based on files or packages. For more
-# details please read the javadoc manpage.
-#
-# 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.
