The package etcd-cpp-apiv3 is compatible with built-in CMake targets:

    find_package(etcd-cpp-api CONFIG REQUIRED)
    target_link_libraries(main PRIVATE etcd-cpp-api)

In cases where you only need the synchronous runtime and want to avoid the initialization
of builtin thread pool, use:

    find_package(etcd-cpp-api CONFIG REQUIRED)
    target_link_libraries(main PRIVATE etcd-cpp-api-core)
