Hi @autoantwort

Thanks for posting this issue.

CMake Error at CMakeLists.txt:17 (message):
  Unknown processor: arm64

set(KNOWN_PROCESSORS x86 x86_64 AMD64 ARM ARM64 i386 armv7l armv7-a aarch64)

Could you please update ARM64 as arm64 in CMakeLists.txt and then try to rebuild libffi?https://github.com/microsoft/vcpkg/blob/master/ports/libffi/CMakeLists.txt#L14

Yes that worked. I have create #16285, can you also look at #16051 :)

Thank you Nancy, had the same issue as autoantwort and the line #14 fix did the trick for me.
