Linking with libbpf v0.8.0 causes deprication warnings. As a temporary
measure, prevent linking with libbpf versions v0.8.0 and greater. This
limitation should be removed in the future when appropriate
compatibility measures are introduced.

It is also removing the find_library() method.
Any reason it was there?
My understanding is that one can't check the library version using that method.
So it was a valid method of picking up the library until now where we always
need to check the version before linking.
OK I see
IMHO checking library version is a bad approach. We should file
the library of whatever version and check for symbols etc in it
and provide corresponding HAVE_ defines to handle it in code.
