Thanks @stella.stamenova for looking into this. I agree the `extend_path` should go back so it properly becomes the install dir. I can't think why I removed it in the first place! The point was to not export the other var, and indeed having that one properly alternate between the build dir vs install dir is why we can get rid of exporting the other one.
