following a few discussions, an extra warning has been added in the release notes per https://gitlab.com/libtiff/libtiff/-/merge_requests/506:
Some CMake related changes, in particular related to the CMake config file now installed, should be considered as a preview and may change in the next releases based on user feedback.
See discussion in https://gitlab.com/libtiff/libtiff/-/merge_requests/496 and https://gitlab.com/libtiff/libtiff/-/merge_requests/494
My software is free, but my time generally not.
