LPCNet Check CMAKE_OSX_ARCHITECTURES and only define relevant optimizations

Per previous PLT discussion, this PR reimplements #57 in a manner that should have lower impact:

The lowest supported macOS release is set to 10.5 unconditionally. CMake/Apple Clang from personal experience will use the minimum supported version of the SDK for each architecture provided in CMAKE_OSX_ARCHITECTURES.
CMAKE_OSX_ARCHITECTURES is set to x86_64 and arm64 unless specifically overridden at the command line (i.e. cmake -DCMAKE_OSX_ARCHITECTURES=ppc\;ppc64 ..)
*_PRESENT is only enabled for the relevant architectures based on the contents of CMAKE_OSX_ARCHITECTURES.
The README file has been updated to clarify that only x86 and ARM are officially supported.

CC @drowe67 to review proposed README contents.

@barracuda156, feel free to give this a shot and see how it goes.

BTW, I compiled this PR into codec2/freedv-gui and it appears I can still decode the example 2020 WAV file on macOS. Additionally, forcing the minimum macOS version to 10.5 doesn't seem to have affected x86_64 and ARM builds as the compiler automatically chose higher versions as approrpiate:

Thanks @tmiw - README looks fine.

Thanks @tmiw - README looks fine.

Cool. Once @barracuda156 confirms that this PR works, it can be merged.

@tmiw Applying just changes to CMakeLists from eecf55d1a935e9d786a19081b41c797ae74b2d2b I still get an error due to Neon flags picked:

You'll need to add the following to the CMake call:

-DBUILD_OSX_UNIVERSAL=1 -DCMAKE_OSX_ARCHITECTURES=ppc\;ppc64

You'll need to add the following to the CMake call:
-DBUILD_OSX_UNIVERSAL=1 -DCMAKE_OSX_ARCHITECTURES=ppc\;ppc64

@tmiw The problem is here: https://github.com/drowe67/LPCNet/blob/eecf55d1a935e9d786a19081b41c797ae74b2d2b/CMakeLists.txt#L131

We cannot assume that the build must be universal; in fact, it is possible only on G5 and 10.5, and even then building just for ppc64 will likely be preferred. However, non-universal builds have not been addressed here (I am sorry, I overlooked that too when saw the changes).

I.e. requiring -DCMAKE_OSX_ARCHITECTURES= for PPC is perfectly okay, but it can be – and usually will be – just one arch, not both.

@barracuda156, how about now?

I haven't heard anything yet so I'm going to assume we're good. @drowe67, okay to merge?

Aug 31 '23 19:08 tmiw

@tmiw Sorry, missed the message. I will check this tomorrow. Away from my PPC hardware atm, but I think this can work in Rosetta too.

@tmiw - yes I'm OK if you want to merge.

Building from eecf55d1a935e9d786a19081b41c797ae74b2d2b On Rosetta it does not work, unfortunately: arch gets misdetected, disabling optimizations is ignored (despite -DCMAKE_OSX_ARCHITECTURES="ppc" being passed) and build fails:

In that commit, CMAKE_OSX_ARCHITECTURES is ignored unless BUILD_OSX_UNIVERSAL is set to 1. The latest change I pushed will set BUILD_OSX_UNIVERSAL to 1 if you override CMAKE_OSX_ARCHITECTURES. Try again?

The latest change I pushed will set BUILD_OSX_UNIVERSAL to 1 if you override CMAKE_OSX_ARCHITECTURES

@tmiw We will not want to force universal build, to be honest. To begin with, it simply cannot work with GCC, regardless of the arch, since no GCC after gcc-4.2 supports universal builds. Leaving compiler issue aside, what even will be universal on 10.4 and 10.6 (when building for PowerPC)? Only 10.5 SDK supports ppc64. Then, only on G5 it is meaningful to build for it, since on G4 64-bit binaries won’t run.

Logically, IMO, we just need to provide an option to override defaults via configure (i.e. avoiding manual hackery). Let defaults be whatever makes better sense, and if implementing logic to detect architecture is problematic or undesirable, then just provide a configure switch to make things work in a non-default case.

In fact, something like if (CMAKE_SYSTEM_PROCESSOR MATCHES "ppc|ppc64" OR (APPLE AND CMAKE_OSX_ARCHITECTURES MATCHES "ppc")) will take care of PowerPC detection (or its negation to make sure Intel-specific options are not forced on PPC). But if that is not acceptable, then, I guess, just allow to set arch manually and disable Intel flags – for those who need that (which cannot possibly hurt anyone, since will never be used automatically). P. S. The OR case unbreaks builds in Rosetta, where CMAKE_SYSTEM_PROCESSOR will be x86, but CMAKE_OSX_ARCHITECTURES will be ppc.

OK, I think it should take into account all current feedback now. Once I get a confirmation that it builds, I'll merge.
