fmt Bazel support

/cc @mihaimaruseac

To get Bazel working with {fmt} you can copy the files BUILD.bazel, WORKSPACE.bazel, .bazelrc, and .bazelversion from this folder (support/bazel) to the root folder of this project.

Is it possible to move those files to the root directory in the upstream repo? Otherwise, we still need a patch in the BCR.

I closed this issue - just wanted to point out that I maintain https://github.com/fmtlib/fmt/blob/master/support/bazel/BUILD.bazel - if there are any changes in {fmt} I will try to adapt it

{fmt} maintainers do not want to have those files in the root dir of {fmt}... unfortunately... (@vitaut we could get rid of the .bazelversion and .bazelrc files if you like - meaning only 2 files (WORKSPACE.bazel and and BUILD.bazel) need to be moved to the root dir - would this be acceptable for you?)

it feels to me like an OSS project is only going to be willing to spend effort on the build system that they use themselves (e.g. adding some tests that prevent them from making changes that break the Bazel build)
so unless they are actually considering switching to Bazel the answer is to follow the typical pattern here and maintain the BUILD file independenty from the project.

I don't think putting build configs for anything other than the main build system (which is CMake for {fmt}) in the top-level directory is a good idea. If limitations of the build system don't allow putting configs in a subdirectory then I suggest creating a separate repo and having {fmt} a submodule.

I don't think this issue should have module wanted on it - fmt already exists in the registry; this issue is about upstreaming the bazel build files to the fmt project.

Ah, well I'm not even sure it makes sense to have issues on this repo which aren't resolvable by making changes to this repo. I think we ought to close it and you could have an issue on the fmt repo about accepting contributions, WDYT?
