cereal is available for most distros https://repology.org/project/cereal/versions, and it provides cmake files.

You should use external package when available.

Latest commit (v4.0.8) uses FetchContent and find_package, can you try it?

Edit: Cereal is optional from 4.0.8, so you need to use -Dspoa_use_cereal=ON to build with.
