It isn't luck - I know exactly what I did to my package manage to get that file installed into two different locatian. I know exactly which -I options I passed to the compiler causes that one file to be found in different locations depending on quotes or brackets to be used. And it works great if I don't use pragma.

i also know why I had to do that aweful abuse to what anyone sane would call wholesome. I don't like it but there are other things going on and I don't want to talk about it anymore.
