'What is the best practive in bazel to overwrite the copts of an external dependency?
Suppose I have a workspace(name == "foo") who requires an external lib "bar".
In the workspace I declair a cc_binary(name = "baz", deps = ["@bar"]).
"bar" is a static library (".lib" on Windows or ".a" on Linux), but I want to compile bar.a with the same copts as "baz". For example on Windows, one may want to use /Qspectre flags or /D_UNICODE to compile baz.lib.
One way is to overwrite --copts in .bazelrc file or command line, but it will apply to all targets.
Another possible way is to use a new BUILD file for "bar", but I wonder what's the best practice to do so?
