Error when compiling SerenityOS fuzzer multiple definition of __sanitizer_cov_trace_const_cmp

[CityOfLight77]

When I compiling SerenityOS with StdFuzzer it return an error. Here is command I used to compile SerenityOS

sudo apt-get install -y libboost-all-dev build-essential cmake curl e2fsprogs libmpfr-dev libmpc-dev libgmp-dev ninja-build unzip qemu-system-i386 qemu-utils ccache rsync libgsf-1-dev
git clone https://github.com/SerenityOS/serenity.git; cd serenity
cmake -GNinja -S Meta/Lagom -B Build/lagom-fuzzers \
  -DBUILD_LAGOM=ON \
  -DENABLE_FUZZER_SANITIZER=ON \
  -DENABLE_ADDRESS_SANITIZER=ON \
  -DCMAKE_CXX_COMPILER=$HOME/StdFuzzer/target/release/libafl_cxx \
  -DCMAKE_C_COMPILER=$HOME/StdFuzzer/target/release/libafl_cc
cd Build/lagom-fuzzers
ninja

Here is the error log

You are linking this one and libfuzzer together in the same binary, remove -fsanitize=fuzzer
