Build broken from tarball download

[SamWhited]

If you download the tarball from the releases page and try to build the build fails because the build file for lora does not exist since the submodule isn't initialized.

@SamWhited you can get the submodules by running git submodule update --init --recursive

@NathanBnm this is in the source tarball, there are no submodules because it's not a git repo.
