I currently have boost installed through brew of which kicad uses
libboost_context-mt.dylib
this library then depends on
libboost_chrono-mt.dylib
the otool -L for libboost_context-mt.dylib for chrono is
@loader_path/libboost_chrono-mt.dylib
After having numerous issues with trying to get this working as it kept
saying that @loader_path/libboost_chrono-mt.dylib was not found, I was
doing some testing with the help of Lewoco and found a few things
BundleUtilities.cmake requests a list of prerequisites using
get_prerequisites and theoretically this should return the full path that
was found in gp_resolve_items (from get_prerequisites) however due to how
get_prerequisites functions the full path is not being added to the
prerequisites_var which is "returned".
I believe this has to do with
gp_append_unique(${prerequisites_var} "${item}")
as that would add the @loader_path version of the path rather than the
resolved path. And when its recursive, and so the full path is then used in
a recursive call to get_prerequisites the function doesn't allow it to add
itself to the list.
unfortunately i don't understand enough about how the function actually
works to know the best way to patch this but i assume it would be better if
only resolved items were added to the prerequisite_vars as otherwise its
possible they would not have enough information to be resolved later
If i am missing something or have made a mistake somewhere please let me
know
thanks
Simon
