thx. I forked the master, and I will try to integrate your branch too mine as well. I did focus the configuration and AppKit/objc too. Slightly offtopic here, but:
I have strategic questions mainly.
- are the .mm files objc files ? Is it documented what are the goals there? I wrote a test.cpp and test.mm and tried to compile it, and got errors with MacOs13.1 Sdk. So, I am wondering how you could compile these nowadays...
-this project doesn't use autoconf, and unused libs are not disabled automatically or command line way, rather it tries to remove the pkg-config --libs part with sed. So, is it a strategy here to manage library depandancies , in example if someone installed libpng or not?
- Finding1: only the lib part is removed by sed, but --cflag part is not consistent with those.
- Finding2: the text is not matching at --cflag replacement line, because of the makefiles content has been changed meanwhile.
My version of configure_makefile contains this now (but this is not the final version, probably it could be a base for further discussions):

My sandbox is mainly for learn how to help you the best. For example, how can I get your commits before it's merged, etc. Also, even if was able to eliminate all of the compilation errors, I got linker erros. So, first I have to understand how the AppKit c++/objc is working in u++. Therefore I have not plan to provide pr now, but at least I would like to learn what is missing at my sandbox.
(the last released mac binaries are working on my mac, but I am not sure, if it is M2 arch rather it is intel and using some rosetta virtualization on my cpu.. So, before I can help anything, I would like to go through several integration related questions first.)
my fork/sandbox is here: https://github.com/bfarago/ultimatepp/tree/IntegrationTest_o n_Mac_M2
Compare to the master: https://github.com/ultimatepp/ultimatepp/compare/master...bf arago:ultimatepp:IntegrationTest_on_Mac_M2
I did not committed all of my other local changes here, because I've plan to rebase to yours or master branch solution rather.
Happy new year!
