--------------------------+----------------------
 I noticed that [https://ports.macports.org/port/ispc/builds builds] for
 ispc 1.16.0 failed on macOS 10.15 and earlier: the SDK version fails to be
 detected, and this leads to trying to build ARM support when the SDK
 doesn’t support it:

 {{{
 -- Using macOS SDK path
 /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk
 -- MacOS_SDK version:
 CMake Warning at CMakeLists.txt:166 (message):
   MacOS SDK version was not detected, assuming 11.0, enabling ARM support
 }}}

 (I personally do not use this port.)
