Error While Linking with Cmake

Describe the bug While trying to link the lib with my project,it happens that

Steps to reproduce the bug The CmakeLists.txt is as below

cmake_minimum_required(VERSION 3.10)
project(pir)
set(GMP_LIBRARY_DIR /usr/local/lib)
set(GMP_INCLUDE_DIRS /usr/local/include)
set(SSL_LIBRARY_DIR /usr/local/lib)
set(SSL_INCLUDE_DIRS /usr/local/include/openssl)
include_directories(${GMP_INCLUDE_DIRS})
include_directories(${SSL_INCLUDE_DIR})
link_directories(${GMP_LIBRARY_DIR})
link_directories(${SSL_LIBRARY_DIR})
add_executable(${PROJECT_NAME} test.cpp)
target_include_directories(${PROJECT_NAME} PUBLIC /home/ydcy/libscapi/include)
target_link_libraries(${PROJECT_NAME} /home/ydcy/libscapi/libscapi.a ${SSL_LIBRARY_DIR}/libssl.a ${GMP_LIBRARY_DIR}/libgmp.a)

and the c++ code is

int PRP(int in){
    PseudorandomPermutation* prp = new LubyRackoffPrpFromPrfVarying();
    vector<byte> *input = new vector<byte>(reinterpret_cast<byte*>(&in), 
                    reinterpret_cast<byte*>(&in) + sizeof(int));
    vector<byte> *output = new vector<byte>(4);
    byte *buffer = new byte[4];
    buffer[0] = 0x01;
    buffer[1] = 0x02;
    buffer[2] = 0x03; 
    buffer[3] = 0x04;
    SecretKey *key = new SecretKey(buffer,4,prp->getAlgorithmName());
    prp->setKey(*key);
    prp->computeBlock(*input,0,*output,0);
    int out;
    memcpy(&out, output->data(), sizeof(int));
    delete(input);
    delete(output);
    delete(prp);
    prp = nullptr;
    input = nullptr;
    output = nullptr;
    return out;
}
