Hi Major,
note, that I'm not a member of the packager group yet and this is one of the reviews I have to write to become one. Therefore, some of my suggestions or remarks may not be perfect. Thank you for understanding and patience until some official member responds to your review request (and reviews my review).

The spec file looks great! I have only a few remarks:

* I see that you explicitly disable bundled unit tests. You should try to enable them or provide a reason for not doing so. See https://docs.fedoraproject.org/en-US/packaging-guidelines/#_test_suites.

* Could you provide a Koji build to demonstrate that all architectures can be built successfully? (Your COPR build is x86_64 only.)

* rpmlint issues following warning: library-not-linked-against-libc /usr/lib64/libcrc32c.so.1.1.0

* Just a nitpick: It may be useful to replace all occurrences of google-crc32c by %{name}.

Everyone starts somewhere! 🎉 Thanks for having a look.

The Arch Linux folks disabled them, too, and it's because the repo brings in extra requirements via submodules which end up being installed in the final package. Even if you package 'googletest', the cmake stuff will need to be heavily patched to use it. I'll add some commentary in there about that.

Here's a new COPR build from this morning with everything included:

  https://copr.fedorainfracloud.org/coprs/mhayden/python-google-cloud/build/2353456/

I sent a scratch build through Koji, too:

I'm not entirely sure how to correct this or how big of an issue it might be.

Good point. I'll go back through and use that more often.

For what it's worth, this warning doesn't seem to be a huge problem from some other reviews I've read. Here's an example: https://bugzilla.redhat.com/show_bug.cgi?id=1968612
