# actually built against. The top-level Makefile names a version, the tree
# under vendor/git records its own, and the submodule is pinned to a tag, so
# all three have to agree or cgit is being built on something other than what
# it claims. Set CGIT_TEST_NO_GIT_VERSION to YesPlease when Git comes from
# elsewhere and the comparison has nothing to say.
