rGd74f2d0a8609: [benchmark] Disable CMake get_git_version
rL364742: [benchmark] Disable CMake get_git_version

Summary

Disabled CMake get_git_version as it is meaningless for this in-tree
build, and hardcoded a null version.

Not using get_git_version avoids a refresh of the git index that is
executed by get_git_version. Refreshing the index can take a
considerable amount of time if the index needs to be refreshed
(particularly with the mono repo). This situation can arise when
building shared source on a host in VMs.

andrewng mentioned this in D63657: [benchmark] Change GetGitVersion to only check "dirty" when a tag is found.Jun 28 2019, 4:27 AM

Sorry for the delay with the original patch!
I think this is fine.
@kbobyrev - any thoughts?

This revision is now accepted and ready to land.Jun 28 2019, 4:38 AM

The change looks good to me, thank you for the patch!

I think I missed the original discussion regarding some benchmark library changes due to a complete lack of time, apologies for that.
