Issues compiling Procamp SDK GPU Example on Mac

I'm using Mac OS version 11.6, XCode 13.0, the SDK from March 30, 2021, and have tried several versions of BOOST (1.78 and 1.67).

To install boost, I downloaded the .tar.bz2 file, cd'ed into "/usr/local/Cellar" and ran the following command:

tar --bzip2 -xf /Users/clong1/Downloads/boost_1_67_0.tar.bz2 

Then, as the instructions say, in XCode I created a custom path linking to my boost folder:

The error says: 

fatal error: 'boost/preprocessor/list/for_each.hpp' file not found

I have seen other forums posts that this may only work when trying to compile in older versions of XCode, however I need to use the newest version in order to support MFR and M1 compatability. 

Any help appreciated!
