Usually, Apple deprecates and then removes on the next release. This means Catalina should have dropped it, but it didn't. So far, there are no signs that Apple is removing OpenCL and OpenGL, so I'd say let's keep it until they actually do - by that time, there might also be updated upstream that uses Metal 2 instead.

OK, I suppose it makes sense to keep it as long as it is around.  I’m not sure where to look on MacOS to tell, though.

With a dependency on Apple’s OpenCL, it seems that we perhaps can remove hacks.mk.  However, the comment suggests that may be unwise.  It all builds and packages fine for me on 10.15 without hacks.mk, but there may be older (pre 10.X?) systems for which this is not true.

I would appreciate someone with a better understanding looking this over to see what part of hacks.mk (if any) should be kept.

Thanks a lot.

Cheers,
