Thank you for the response! If you are able/willing to upload the source code to a github, that will allow people to 'fork' it and still attribute you very easily. Any SFX that isn't under the same license or is under something different can be placed in a separate download on a file hosting service (provided that you're permitted to do so) otherwise note down that it isn't included and which files are missing so the community can replace them in their own builds.
Build instructions are often vital but also left out of public source code posts so having that would also help :)
