Unable to compile the library on arm64-windows

[GiulioRomualdi]

I'm trying to port CppAD on vckg. The compilation on arm64 - windows platform fails with the following error

-- cppad_tape_id_type_is_unsigned = 0
-- Warning: using a signed cppad_tape_id_type is for CppAD developers only !
-- Performing Test cppad_tape_addr_type_is_unsigned

The warning says you are using a signed type for cppad_tape_addr_type
https://coin-or.github.io/CppAD/doc/cmake.htm#cppad_tape_id_type

The error says you are using a value less than 4 for cppad_max_num_threads
https://coin-or.github.io/CppAD/doc/cmake.htm#cppad_max_num_threads

What were the settings for these two types in your cmake command ?
