Hi, thank you for trying OpenAT! Yes I can help you for sure:

The problem is:

missing template arguments before ‘(’ token
return std::pair(res["status"].get<deposit_status_t>(),

at the line return std::pair I'm omitting the types for the template type pair because C++17 is able to automatically deduct the right type (http://en.cppreference.com/w/cpp/language/class_template_argument_deduction).

The problem is, hence, that your compiler do not support completely C++17.
In my setup, I've tested it with clang 5 and gcc 7 and works well.

Also, the compiler must be specified when running cmake and not make, hence:

mkdir build
cd build
CC=clang CXX=clang++ cmake  ..
make

If clang is newer enough, it will work.
