Re: CMakeLists.txt in libobjc2

[Mathias Bauer]

Hi David,

thanks for your helpful explanation. If it's just about optimization, 
then I probably won't use that. I just was irritated by the term 
"options". As long as I still need to find out why I can't compile with 
clang on ARM as needed, I will try to catch every bit of information 
that I can get to learn more about the tools I'm trying to use.

Best regards,
Mathias
