# - 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( ) # 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( ) # Makes a copy of the bundle at location and then fixes up the # new copied bundle in-place at ... # # VERIFY_APP() # Verifies that an application appears valid based on running analysis # tools on it. Calls "message(FATAL_ERROR" if the application is not verified. # # GET_BUNDLE_MAIN_EXECUTABLE( ) # 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( ) # 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( ) # 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 and the path to its main executable in # # # GET_BUNDLE_ALL_EXECUTABLES( ) # Scans the given bundle recursively for all executable files and accumulates # them into a variable. # # GET_ITEM_KEY( ) # 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() # 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( # ) # 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( ) # Loop over all the executable and library files within the bundle (and given # as extra ) 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( ) # 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( ) # 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( ) # 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( ) # 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( ) # 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. #============================================================================= # Copyright 2008-2009 Kitware, Inc. # # Distributed under the OSI-approved BSD License (the "License"); # see accompanying file Copyright.txt for details. # # This software is distributed WITHOUT ANY WARRANTY; without even the # implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. # See the License for more information. #============================================================================= # (To distribute this file outside of CMake, substitute the full # License text for the above reference.) # The functions defined in this file depend on the get_prerequisites function # (and possibly others) found in: # get_filename_component(BundleUtilities_cmake_dir "${CMAKE_CURRENT_LIST_FILE}" PATH) include("${BundleUtilities_cmake_dir}/GetPrerequisites.cmake") function(get_bundle_main_executable bundle result_var) set(result "error: '${bundle}/Contents/Info.plist' file does not exist") if(EXISTS "${bundle}/Contents/Info.plist") set(result "error: no CFBundleExecutable in '${bundle}/Contents/Info.plist' file") set(line_is_main_executable 0) set(bundle_executable "") # Read Info.plist as a list of lines: # set(eol_char "E") file(READ "${bundle}/Contents/Info.plist" info_plist) string(REGEX REPLACE ";" "\\\\;" info_plist "${info_plist}") string(REGEX REPLACE "\n" "${eol_char};" info_plist "${info_plist}") # Scan the lines for "CFBundleExecutable" - the line after that # is the name of the main executable. # foreach(line ${info_plist}) if(line_is_main_executable) string(REGEX REPLACE "^.*(.*).*$" "\\1" bundle_executable "${line}") break() endif() if(line MATCHES "^.*CFBundleExecutable.*$") set(line_is_main_executable 1) endif() endforeach() if(NOT "${bundle_executable}" STREQUAL "") if(EXISTS "${bundle}/Contents/MacOS/${bundle_executable}") set(result "${bundle}/Contents/MacOS/${bundle_executable}") else() # Ultimate goal: # If not in "Contents/MacOS" then scan the bundle for matching files.
