Usage: third_party_libs_tool [OPTION] BUNDLE.app
Bundle third party dylibs into BUNDLE.app and fix up linkages.
Binaries are searched for in BUNDLE.app/Contents/MacOS .
The dylibs are copied into BUNDLE.app/Contents/Frameworks .
-h, --help, --usage Show this help screen and exit.
-v, --version Show version information and exit.
-l, --list Only list dylibs used by binaries, do not copy or link.
Examples:
third_party_libs_tool ./MyApp.app # bundle and link ./MyApp.app
third_party_libs_tool --list ./MyApp.app # list third party libs used by ./MyApp.app
