error: undefined reference to 'google::protobuf::ShutdownProtobufLibrary()

Question

While building the protobuf and protobuf-c and clang. I'm facing some error. What my guess is I'm unable to link the protobuf while invoking the cmake for building clang despite me passing -L/usr/local/lib this flag. And my protobuf is installed in /usr/local/lib.

I'm using Ubuntu 22.04.2 LTS.

G++ version: g++ (Ubuntu 8.4.0-3ubuntu2) 8.4.0

The code for protobuf and protobuf-c build:

echo
echo -e "${BLUE}===================== build protobuf ======================${NC}"
echo

if [  -f ${PWD_PATH}/succeed/protobuf ]; then
    cd $PWD_PATH
    # eval "git clone https://github.com/protocolbuffers/protobuf.git"
    eval "cd protobuf && git checkout v3.15.8 && git submodule update --init --recursive && ./autogen.sh"
    eval "./configure && make -j$(nproc) &&  sudo make install && sudo ldconfig"
    echo "done" > ${PWD_PATH}/succeed/protobuf
fi

echo
echo -e "${GREEN}[*] build protobuf succeed!${NC}"

# build protobuf-c
echo
echo -e  "${BLUE}===================== build protobuf-c =======================${NC}"
echo
cd $PWD_PATH


if [  -f ${PWD_PATH}/succeed/protobuf-c ]; then
    echo "git clone https://github.com/protobuf-c/protobuf-c.git"
    # eval "git clone https://github.com/protobuf-c/protobuf-c.git"
    # export LD_RUN_PATH=/usr/local/lib
    # export LD_LIBRARY_PATH=/usr/local/lib/
    # export LD_LIBRARY_PATH=/usr/local/lib/:$LD_LIBRARY_PATH
    eval 'cd protobuf-c && git checkout v1.4.0 && ./autogen.sh && ./configure && make -j$(nproc) && sudo  make install'

    eval 'sudo ln -sf /usr/local/lib/libprotobuf-c.so.1.0.0 /usr/lib/libprotobuf-c.so.1'
    echo "done" > ${PWD_PATH}/succeed/protobuf-c
fi

echo
echo -e "${GREEN}[*] build protobuf-c succeed!${NC}"

The code for building clang:

echo -e "${BLUE}======================= build clang ===============================${NC}"
echo

BINUTILS_PATH=${PWD_PATH}/binutils-2.30
