# Libdwarf needs zstd, cpptrace doesn't, and libdwarf has its own Findzstd but it doesn't define zstd::libzstd_static /
# zstd::libzstd_shared targets which leads to issues, necessitating a find_dependency(zstd) in cpptrace's cmake config
# and in order to support non-cmake-module installs we need to provide a Findzstd script.
