From de3c48d72ec7064e7f0522877fe759c729df0c50 Mon Sep 17 00:00:00 2001

Subject: [PATCH] Allow using a system provided libgit2 library
Setting the USE_SYSTEM_LIBGIT2 Make or CMake variable (through the
BUILD_OPTIONS variable) to any value enables using the system library.
The default behavior of using a bundled copy of libgit2 is unchanged.
