Do we need to have JSON sources to be included here in auth as well? It's currently in core, but does it work with visibility=hidden?

Nice catch! Looks like it should be in all projects. Not sure how to verify on CI because in tests we are accessing not exposed classes.
Locally added set (CMAKE_CXX_VISIBILITY_PRESET hidden) to the top-level CMakeLists.txt and got several unresolved external symbols building olp-cpp-sdk-authentication. And no unresolved symbols reported with this magic header added to the authentication project.
Tried on macos clang, because previously unresolved symbols were mainly met on clang builds.
