This PR adds a Findzstd.cmake script to cpptrace's install so that `find_dependency(zstd)` can succeed on installations that don't include zstdConfig.cmake/zstd-config.cmake. The reason `find_dependency(zstd)` is needed in cpptrace's config, despite `find_dependency(zstd)` also being in libdwarf's cmake and cpptrace not needing zstd, is that libdwarf's cmake doesn't define `zstd::libzstd_static` / `zstd::libzstd_shared` targets. This should fix #112.

# 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.
