tesseract support for apple m1

[Konstantin Limarev]

Can tesseract be compiled on apple m1 machine?

I'm trying to install tesseract-4.1.1 via vcpkg on Apple M1 and it fails at OptimizeForArchitecture.cmake:

`exec_program("/usr/sbin/sysctl -n machdep.cpu.vendor machdep.cpu.model machdep.cpu.family machdep.cpu.features" OUTPUT_VARIABLE _sysctl_output_string)`  

And this is absolutely normal since 

Apple M1 output of `sysctl -a | grep machdep.cpu`:

machdep.cpu.brand_string: Apple M1

machdep.cpu.core_count: 8

machdep.cpu.cores_per_package: 8

machdep.cpu.logical_per_package: 8

machdep.cpu.thread_count: 8

differs from Intel-based one:
