How can an executable be included in the PATH using Bazel?

edit

To include an executable in the PATH using Bazel, you can use the data attribute in the cc_binary rule.

For example, if you have a binary called hello in the src directory, you can modify your cc_binary rule in your BUILD file like this:

cc_binary(
    name = "hello",
    srcs = ["src/hello.cpp"],
    data = [":hello"],
)

In this example, the data attribute specifies that the hello binary should be included in the target directory, i.e., the bin directory created by Bazel when building the target.

To include the binary in the PATH, you can create a shell script that adds the bin directory to the PATH and then calls the binary. For example:

#!/bin/bash

export PATH=$PATH:$(pwd)/bazel-bin

hello "$@"

Assuming this script is in your PATH, you can now run the hello binary from anywhere on your system.
