Bazel support

[Icantjuddle]

I've integrated the tracy client successfully into my organization's bazel setup. I'd like to add it back for anyone else who uses bazel. Is adding a third (fourth?) build system too much of a maintenance burden? Where would it be best to add it?

[sibi-venti]

can i have the bazel build files/? you can create a new branch called bazel, I guess it wont have any conflicts

Sure I'll push it sometime today.

@Icantjuddle is it pushed ?

You'll also need a workspace rule which can be included as:

load("@bazel_tools//tools/build_defs/repo:http.bzl", "http_archive")

def tracy_workspace():
    http_archive(
        name = "com_github_tracy",

        sha256 = "de182a4ddd9850f0f4fa584cb0b6306be4995c1b42a4bcdee780041afcfa7834",
        strip_prefix = "tracy-0.10",
        urls = ["https://github.com/wolfpld/tracy/archive/refs/tags/v0.10.zip"],
    )
