c++ – Undefined symbols for structure arm64 whereas constructing cpp thrift lib for iOS

I’m attempting to construct a number of lib for iOS however I get error for thrift lib model 0.21.0

beneath is the config that I’m utilizing to construct it

ExternalProject_Add(thrift
        SOURCE_DIR ${CMAKE_CURRENT_SOURCE_DIR}/${THRIFT_DIR}
        INSTALL_DIR ${THIRDPARTY_INSTALL_DIR}
        CMAKE_ARGS ${EXTERNAL_PROJECT_CMAKE_ARGS}
            -DOPENSSL_ROOT_DIR=${OPENSSL_INSTALL_DIR}
            -DOPENSSL_CRYPTO_LIBRARY=${OPENSSL_INSTALL_DIR}/lib/libcrypto.a
            -DOPENSSL_SSL_LIBRARY=${OPENSSL_INSTALL_DIR}/lib/libssl.a
            -DBoost_INCLUDE_DIR=${BOOST_INCLUDE_DIR}
            -DWITH_ZLIB=${ZLIB_INSTALL_DIR}
            -DCMAKE_FIND_LIBRARY_SUFFIXES=".a"
            -DBUILD_SHARED_LIBS=ON
            -DBUILD_JAVA=OFF

            -DBUILD_QT=OFF
            -DBUILD_QT4=OFF
            -DBUILD_RUBY=OFF
            -DBUILD_PHP=OFF
            -DBUILD_SWIFT=OFF
            -DBUILD_TESTING=OFF
            
            BUILD_COMMAND make clear && make CFLAGS+=-DOPENSSL_NO_SSL3 CFLAGS+=-fPIC CXXFLAGS+=-DOPENSSL_NO_SSL3 CXXFLAGS+=-fPIC
        INSTALL_COMMAND make set up
    )

I get error

But when I -DBUILD_SHARED_LIBS=ON to -DBUILD_SHARED_LIBS=OFF it builds efficiently however it creates solely .a lib not .dylib that’s required for an additional lib

Any assist or route can be appreciated
