# BundleUtilities
# ---------------
#
# 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
# get_item_rpaths
# 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> [<rpaths>])
#
# 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.
