Bazel updates

[louwers]

• Update Bazel
• Update Bazel dependencies
• Get rid of WORKSPACE so Renovate can auto-update

[keith]

nice!

@keith Apparently auto-updates don't work when you have both a WORKSPACE and a MODULE.bzl. It is a miracle everything still worked. Hehe.

Are there any guidelines on how to make this build work with MacPorts? I don't have Homebrew meaning libuv as defined in MODULE.bazel cannot be found.

[louwers]

@bdon You can also use CMake to build for macOS. I can write some instructions.

[bdon]

That would be really helpful. I was attempting to patch MODULE.bazel with something like this:

new_local_repository(
    name = "libuv",
    build_file_content = """
cc_library(
    name = "libuv",
    hdrs = [
        "include/uv.h",
        "include/uv/darwin.h",
        "include/uv/errno.h",
        "include/uv/threadpool.h",
        "include/uv/unix.h",
        "include/uv/version.h",
    ],
    srcs = [
        "lib/libuv.a",  # Static library from MacPorts
    ],
    includes = ["include"],
    visibility = ["//visibility:public"],
)
""",
    path = "/opt/local",  # MacPorts path for libuv
)

But haven't had any success yet.

The GLFW app crashes on macOS with Metal if you use CFRunLoop. I haven't been able to figure out why, that is why I changed the macOS Bazel build config to use libuv. Ideally we change it to compile libuv from source instead...

Anyway, if you the CMake build config uses CFRunLoop. As said the GLFW app crashes when used with Metal. But if you have MoltenVK installed you can use Vulkan instead...
