I am trying to compile libgit2 with GSSAPI enabled for macOS, but I can't seem to get it working. It looks like macOS provides a kerberos framework that was first available in macOS 10.0, which is what I'd expect libgit2 to use when trying to find GSSAPI on mac. However, FindGSSAPI.cmake doesn't appear to be looking for that framework, and the default UNIX case doesn't work on my mac.

Is there a way to get this working using the existing cmake build that I'm not aware of?

Reproduction steps

cmake -DUSE_GSSAPI=ON ..

Expected behavior

To find GSSAPI and enable SPNEGO authentication support.

Actual behavior

Doesn't find GSSAPI.

Version of libgit2 (release number or SHA1)

0.28.2

Operating system(s) tested

macOS 10.14.6
