Hi @paulross80

Thanks for your report.
This is not a bug in Conan, but a ConanCenter recipe that has not been updated to be 2.0 ready yet.
Updating recipes to 2.0 is an ongoing effort, so far the efforts are being done on the most downloaded recipes: conan-io/conan-center-index#12888

You can see there that libtool is still not ready. I am closing this issue, please follow up in the conan-center-index repo for progress on this.
