9 months ago OK, I was able to get this to build by passing in a bunch of -D options. Why they were not found by default on AARCH64 is a mystery still.
CMakeLists.txt has one error in it that breaks on ARM64: Essentially, I had to remove two flags to GCC
-maccumulate-outgoing-args -mno-red-zone
IN the block that starts with if(CMAKE_SYSTEM_NAME MATCHES "Linux") SET(CMAKE_EXE_EXPORTS_C_FLAG "")
The following Diff got me past it.

Usually the explanation would be in the README. Barring that, it would be in the Documentation file.
I tied building with the obvious : mkdir build; cd build; cmake ..
But quickly got into errors like :
CMake Error at CMakeLists.txt:49 (MESSAGE): Unkown ARCH
Setting the arch gets to:
cmake -DARCH:STRING=aarch64 -DTOOLCHAIN:STRING=gcc .. CMake Deprecation Warning at CMakeLists.txt:1 (cmake_minimum_required): Compatibility with CMake < 3.5 will be removed from a future version of CMake.
Update the VERSION argument value or use a ... suffix to tell
CMake that the project does not need compatibility with older versions.
