# We redirect malloc/free family of functions to different functions that will track memory in ClickHouse.
# It will make this library depend on linking to 'clickhouse_common_io' library that is not done explicitly via 'target_link_libraries'.
# And we check that all libraries dependencies are satisfied and all symbols are resolved if we do build with shared libraries.
# That's why we enable it only in static build.
# Also note that we exploit implicit function declarations.
