Merge branch 'patches/docBundleUtilities'

of http://github.com/themiwi/CMake
into fix-10747

Conflicts:
	Modules/BundleUtilities.cmake

There was one newly added function in BundleUtilities.cmake
which also needed the same "documentation at top" treatment.

# Requires CMake 2.6 or greater because it uses function, break and

#
# 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.
#
# 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 return a dir at
# the same level as the executable, named with the executable's base name and
# ending with ".app"
#
# 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.)
#
# 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.
#
# 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.
