Building issues on OSX

[rudy cortes]

Hello folks. 

I've downloaded the code and followed the build instructions. Regrettably, running into errors at the linking stage, I believe. Any help or pointers yall can provide is greatly appreciated

Here is some info:

OSX Version: 10.14.6

Log output:

Hi,

We're in the process of resurrecting our Mac builds, which have suffered for a while due to the fact none of us were developing on Mac. As part of this, we're concentrating our limited resources on native Apple Silicon builds, so the prebuilt dependencies at https://github.com/GafferHQ/dependencies/releases/tag/5.0.0 (I presume you're using these, though you don't say) are for Apple Silicon only. The linking error you're getting indicates that you are trying to build for Intel, which would mean needing to build the dependencies yourself, or limiting yourself to earlier Gaffer versions for which prebuilt Intel dependencies are available...

Cheers...

John

That's a pitty.

Tried also to build it on Mac Intel, but as an artist it's not possible to use gaffer anymore :-(
