Build is broken with external dependencies about libavif

[joedrago]

Can you provide a minimal repro case? I'm sure there's a chance I'm missing something in CMake, but the common build paths we're already using are currently working for us.

[brad0]

You're not going to be able to reproduce unless you build on something other than a Linux based Operating System because the compiler config makes assumptions that do not pertain elsewhere.

[brad0]

Actually that is not 100% true. There are some Linux based Operating Systems that install packages into another path other than /usr/local like /opt or something similar where the bug in the CMake build would be exposed.
