[CMake] Problem with fixup bundle and duplicate change commands on macOS

[Luis Caro Campos]

Hi Lukas,

Could you provide some details? Please do correct me if any of my
assumptions are wrong.

You are calling FIXUP_BUNDLE on an executable created this way:
add_executable(MyAppName MACOSX_BUNDLE ...),

and you need are calling FIXUP_BUNDLE so that the 3rd party library
dependencies are pulled into the bundle, so that the bundle becomes
standalone.

Is FIXUP_BUNDLE being called at build time ("make"), perhaps as custom
command that depends on the application target, or install time ("make
install"), as part of the INSTALL(...) directive in a cmake script?

What exactly do you mean by "duplicate commands" ?

In order to make the bundle standalone, I believe FIXUP_BUNDLE iteratively
goes through the dependencies of the main executable, which are 'hardcoded'
in the executable. You can list the depencies using
$ otool -L executableName

For each dependency (dylib shared library or a Framework), the dependencies
will be copied to the Frameworks folder in the bundle, based on their
install name, and the executable will be fixed using install_name_tool to
make sure that non-system libraries are loaded from the Frameworks folder.
If these dependencies have other dependencies, install_name_tool is also
called on them.

Sometimes there are hiccups, and unfortunately in some cases it may be
difficult to produce a truly re-locatable bundle if the install names of
some libraries are not fully "correct".

Regards,
Luis
