Please remove this as a mirror - it's not an official mirror, and the documented way to use it is transparently without modifying the recipes, thanks!

Hi @jcar87, thank you for the review. I just followed the instruction at the top of the conandata file:

# The sources for this project get deleted from time to time.
# We use the backup sources from Conan Center as mirrors to let users compile in the future
# When adding new versions, directly add the URL following previous versions schema
# https://c3i.jfrog.io/artifactory/conan-center-backup-sources/ + sha256 of the sources
# The file will be automatically uploaded after the first successful compilation of the new version
# And will be usable as a mirror from then on.
# At some point the Conan client might come pre-configured with this backup remote by default, but don't delete the links then
# some users might still rely on the old revisions/not have it set to point to our CCI backup remote

I do not know enough about conan to decide if it's a good idea to do that or not. However I think it should be consistent within the file. Meaning if we remove the conan-center-backup-sources url from one version, it should be removed from all versions. For now I prefer following the instructions and let somebody else (in annother PR) decide if all those conan-center-backup-source url's should be removed or not.

According to

#At some point the Conan client might come pre-configured with this backup remote by default, but don't delete the links then
# some users might still rely on the old revisions/not have it set to point to our CCI backup remote`

it would make sense to keep the old conan-center-backup-source links but not add new ones if the conan client comes pre-configured with this backup remote nowadays. Is this the case?
