    I'm trying to import an external dll lpsolve into unity by dragging it into the assets folder and then adding the using statement but I keep getting an error.

    using lpsolve55;

    the type or namespace could not be found

    I've tried 32 and 64 bit dlls. I've also tried dragging the entire folder contents of the dev downloads into unitys assets folder.
