AssertSoo fails when trying to build with a protobuf library in fuzzing mode

[I-ABD-I]

when using fuzzing mode and a proto library, and trying to run it always reports this line:
Assertion failed: ((common.capacity() == policy.soo_capacity()) && "Try enabling sanitizers."), function AssertSoo, file raw_hash_set.cc, line 781.

everything in this cmake was copied from the getting started guide except the protobuf part
