Bug: link_args doesn't work or maybe it is not implemented correctly

[ravi688]

    "targets": [
        {
            "name": "hbkvmctl",
            "is_executable": true,
            "link_args" : [ "-lcurl" ],
            "sources": [
                "source/main.cpp",
                "source/Details.cpp",
                "source/Misc.cpp",
                "source/AppConfig.cpp",
                "source/PersistentConfig.cpp"
            ]
        }
    ]

Here, replacing "link_args" with "windows_args" works, but in the former case, it doesn't. Looking into the documentation, it seems that "link_args" was never handled/implemented.
