    // about C++.  Moreover, it can only happen if someone manually copies files around and
    // messes things up.  If instead they run `make install` or `cmake --build .  --target

    // NOT BUILD A STANDALONE DLIB AND THEN GO CHERRY PICKING FILES FROM THE BUILD FOLDER AND
    // MIXING THEM WITH THE SOURCE FROM GITHUB.  USE CMAKE'S INSTALL SCRIPTS TO INSTALL DLIB.
    // Or even better, don't install dlib at all and instead build your program as shown in
