Optional dependencies
=====================
While the library provides git functionality without the need for
dependencies, it can make use of a few libraries to add to it:
- pthreads (non-Windows) to enable threadsafe access as well as multi-threaded pack generation
- OpenSSL (non-Windows) to talk over HTTPS and provide the SHA-1 functions
- LibSSH2 to enable the ssh transport
- iconv (OSX) to handle the HFS+ path encoding peculiarities
Building libgit2 - Using CMake

for threading.
