# - 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_resolve_embedded_item
|
|
# (projects can override with gp_resolve_embedded_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_IS_FILE_EXECUTABLE_EXCLUDE_REGEX can be set to a regular expression used
|
|
# to give a hint to identify more quickly if a given file is an executable or not.
|
|
# This is particularly useful on unix platform where it can avoid a lot of
|
|
# time-consuming call to "file" external process. For packages bundling hundreds
|
|
# of libraries, executables, resources and data, it largely speeds up the function
|
|
# "get_bundle_all_executables".
|
|
# On unix, a convenient command line allowing to collect recursively all file extensions
|
|
# useful to generate a regular expression like "\\.(dylib|py|pyc|so)$" is:
|
|
# find . -type f -name '*.*' | sed 's@.*/.*\.@@' | sort | uniq | tr "\\n" "|"
|
|
#
|
|
# 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_RESOLVE_EMBEDDED_ITEM(<context> <embedded_item> <exepath> <resolved_embedded_item_var>)
|
|
# Resolve an embedded item into the full path within the full path. Since the item can be
|
|
# copied later, it doesn't have to exist when calling this function.
|
|
#
|
|
# Override on a per-project basis by providing a project-specific
|
|
# gp_resolve_embedded_item_override function.
|
|
#
|
|
# If GP_RPATH_DIR variable is set then item matching '@rpath' are
|
|
# resolved using the provided directory. Currently setting this variable
|
|
# has an effect only on MacOSX when fixing up application bundle. The directory
|
|
# are also assumed to be located within the application bundle. It is
|
|
# usually the directory passed to the 'rpath' linker option.
|
|
#
|
|
# GP_RESOLVED_FILE_TYPE(<original_file> <file> <exepath> <dirs> <type_var>)
|
|
# Return the type of <file> with respect to <original_file>. String
