CMAKE_APPLE_SILICON_PROCESSORΒΆ
New in version 3.19.2.
On Apple Silicon hosts running macOS, set this variable to tell
CMake what architecture to use for CMAKE_HOST_SYSTEM_PROCESSOR.
The value must be either arm64 or x86_64.
The value of this variable should never be modified by project code.
It is meant to be set by a toolchain file specified by the
CMAKE_TOOLCHAIN_FILE variable, or as a cache entry
provided by the user, e.g. via -DCMAKE_APPLE_SILICON_PROCESSOR=....
See also the CMAKE_APPLE_SILICON_PROCESSOR environment variable.
