# - 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
# describing type of prerequisite is returned in variable named <type_var>.
#
# Possible types are:
# system
# local
# embedded
# other
