Library version of ZeroTier
libzt makes it easy to securely connect devices, servers, cloud VMs, containers, and apps everywhere and manage them at scale. We provide a socket-like API supporting SOCK_STREAM, SOCK_DGRAM, and SOCK_RAW. There's no need for system-wide virtual interfaces. This connection is exclusive to your app and fully encrypted via the Salsa20 cipher. For a more in-depth discussion on the technical side of ZeroTier, check out our Manual

We recommend using CMake and clang.
git submodule init
git submodule update
make patch
cmake -H. -Bbuild -DCMAKE_BUILD_TYPE=Release
or possibly:
cmake -H. -Bbuild --config Release
Then
cmake --build build
Builds are placed in bin\lib
