# Installs the logos-protocol headers AND sources in the source-export
# layout ($out/include/cpp/...). This mirrors the layout logos-cpp-sdk has
# always shipped: logos-cpp-sdk's own include output re-exports these files
# at the exact paths downstream build systems (logos-plugin-qt's
# LogosModule.cmake source layout, etc.) already reference, which is what
# keeps the cpp-sdk artifact byte-compatible while the sources live here.
