Hi, when I link libpplcv_static.a to another dynamic lib, it says:

ImportError: /workspace/libxxx.so: undefined symbol: _ZN3ppl6common10LogMessageC1EjPNS0_6LoggerEPKcj

nm /workspace/libxxx.so |grep _ZN3ppl6common10LogMessageC1EjPNS0_6LoggerEPKcj
                 U _ZN3ppl6common10LogMessageC1EjPNS0_6LoggerEPKcj

nm /tmp/ppl.cv/./cuda-build/install/lib/libpplcommon_static.a |grep _ZN3ppl6common10LogMessageC1EjPNS0_6LoggerEPKcj
0000000000000000 T _ZN3ppl6common10LogMessageC1EjPNS0_6LoggerEPKcj

the source

        pplcv_lib_dir=os.path.join(PPLCV_INSTALL, "lib")
        extra_link_args.append(f'-Wl,-rpath={pplcv_lib_dir}')
        extra_link_args.append('-Wl,-Bsymbolic')
