git submodule update --init

This project uses CMake as a build system generator. The scripts build.* simplify building and packaging for various targets. There are many targets and configurations not mentioned here.

Using the host keyword will automatically detect the current machine type and build standard libzt for use in C/C++ (no additional language bindings.) See ./build.sh list for additional target options. libzt depends on cURL for the optional portion of the API that interfaces with our hosted web offering (my.zerotier.com). If you do not need this functionality you can omit it by passing -DZTS_DISABLE_CENTRAL_API=1 to CMake.
