why I can't use select option under http_archive()

[the-code-samurai-97]

hi, I am trying too build a repository based on platforms

http_archive(
               name = "open3d",
               sha256 = select({"@platforms//os:macos": ["e3b0c44298fc1c149afbf4c8996fb92427ae41e4649b934ca495991b7852b855"],
                               "@platforms//os:linux": ["e473031c64ef744f639418321f7731e799a61b1da2fc7b0902e87bbb14a8f16f"]}),
               urls = select({"@platforms//os:macos": ["https://github.com/isl-org/Open3D/releases/download/v0.17.0/open3d-devel-darwin-x86_64-0.17.0.tar.xz"],
                              "@platforms//os:linux": ["https://github.com/isl-org/Open3D/releases/download/v0.17.0/open3d-devel-linux-x86_64-cxx11-abi-cuda-0.17.0.tar.xz"]}),
               build_file = "//third_party/open3d:open3d.BUILD.bzl",
               strip_prefix = select({"@platforms//os:macos": ["open3d-devel-darwin-x86_64-0.17.0"],
                                   "@platforms//os:linux": ["open3d-devel-linux-x86_64-cxx11-abi-cuda-0.17.0"]}),
       )

is there a better way?

http_archive is a repository rule, which means that it can't use select. Instead, just add one http_archive per OS/architecture and then use select in build rules (such as an alias) to select a target from the correct repository.
