# Adapted from the Dolphin project: https://dolphin-emu.org/ # This module can be used in two different ways. # # When invoked as `cmake -P PostprocessBundle.cmake`, it fixes up an # application folder to be standalone.

Any additional shared libraries, like # plugins, that are found under Contents/MacOS/ will be made standalone as well. # # When called with `include(PostprocessBundle)`, it defines a helper # function `postprocess_bundle` that sets up the command form of the # module as a post-build step. if(CMAKE_GENERATOR) # Being called as include(PostprocessBundle), so define a helper function. set(_POSTPROCESS_BUNDLE_MODULE_LOCATION "${CMAKE_CURRENT_LIST_FILE}") function(postprocess_bundle out_target in_target) add_custom_command(TARGET ${out_target} POST_BUILD COMMAND ${CMAKE_COMMAND} -DBUNDLE_PATH="$/../.." -DCODE_SIGN_CERTIFICATE_ID="${CODE_SIGN_CERTIFICATE_ID}" -DEXTRA_BUNDLE_LIBRARY_PATHS="${EXTRA_BUNDLE_LIBRARY_PATHS}" -P "${_POSTPROCESS_BUNDLE_MODULE_LOCATION}" ) endfunction() return() endif() get_filename_component(BUNDLE_PATH "${BUNDLE_PATH}" ABSOLUTE) message(STATUS "Fixing up application bundle: ${BUNDLE_PATH}") # Make sure to fix up any included ImHex plugin. file(GLOB_RECURSE extra_libs "${BUNDLE_PATH}/Contents/MacOS/plugins/*.hexplug") # BundleUtilities doesn't support DYLD_FALLBACK_LIBRARY_PATH behavior, which # makes it sometimes break on libraries that do weird things with @rpath.
