If they can't find you, the code doesn't matter
You need a units library for C++. You search GitHub for "units" and get a wall of repositories, all some variation of the same word, by different authors, with no obvious way to tell which one is alive, which one is serious, and which one will still be maintained next year. You pick one almost at random, or you give up and write your own. The library you needed might have been right there. You just could not find it, or could not tell it apart from the noise.
