error: a nonstatic member reference must be relative to a specific object

Hi, I'm trying to compile this project on Ubuntu18.04, and I've written a Cmakelist.txt：

cmake_minimum_required(VERSION 3.15)
set(CMAKE_CUDA_COMPILER /usr/local/cuda-10.0/bin/nvcc)
set(CMAKE_CUDA_FLAGS -arch=sm_75)
#set(CMAKE_CUDA_FLAGS "${CMAKE_CUDA_FLAGS} -ccbin /usr/local/cuda-10.0/bin/nvcc")
project(COCO_track LANGUAGES CUDA CXX)

set(CMAKE_CXX_STANDARD 17)
set(CMAKE_CUDA_STANDARD 14)

# TensorRT 7
set(TensorRT_7_DIR "/home/xfb/Programs/TensorRT/7.0.0.11")
include_directories("${TensorRT_7_DIR}/include")
set(TensorRT_7_LIBDIR "${TensorRT_7_DIR}/lib")
file(GLOB TensorRT_7_LIBS "${TensorRT_7_LIBDIR}/*.so")

# CUDA 10.0
set(CUDA_DIR "/usr/local/cuda-10.0")
include_directories("${CUDA_DIR}/include")
set(CUDA_LIBDIR "${CUDA_DIR}/lib64")
file(GLOB CUDA_LIBS "${CUDA_LIBDIR}/*.so")

# OpenCV
set(OpenCV_DIR "/usr/local/lib/cmake/opencv4")
find_package(OpenCV REQUIRED)

# Protobuf
set(Protobuf_DIR "/usr/local/include/google/protobuf")
include_directories("${Protobuf_DIR}")
set(Protobuf_LIB /usr/local/lib/libprotobuf.so)

# common files for sample projects
include_directories(builder caffeplugin common examples infer onnx_parser)
include_directories(${PROJECT_SOURCE_DIR})

file(GLOB caffeplugin_src "caffeplugin/*.cpp" "caffeplugin/plugins/*.cu")
file(GLOB common_src "common/*.cpp")
file(GLOB infer_src "infer/*.cpp" "infer/*.cu")
file(GLOB examples_src "examples/*.cpp")
file(GLOB onnx_src "onnx/*.cpp")
file(GLOB onnx_parser_src "onnx_parser/*.cpp" "onnx_parser/*.cu")
file(GLOB onnxplugin_src onnxplugin/onnxplugin.cpp "onnxplugin/plugins/*.cu")

add_executable(COCO_track
        builder/trt_builder.cpp
        ${caffeplugin_src}
        ${common_src}
        ${examples_src}
        ${infer_src}
        ${onnx_src}
        ${onnx_parser_src}
        ${onnxplugin_src}
        import_lib.cpp
        main.cpp
        )

target_link_directories(COCO_track PUBLIC builder caffeplugin common examples infer onnx onnx_parser)
target_link_directories(COCO_track PUBLIC "${TensorRT_7_DIR}/include")
target_link_directories(COCO_track PUBLIC "${CUDA_DIR}/include")
target_link_directories(COCO_track PUBLIC "${Protobuf_DIR}")
target_link_libraries(COCO_track ${TensorRT_7_LIBS} ${CUDA_LIBS} ${OpenCV_LIBS} ${Protobuf_LIB})

However, when I built the project, I met the following error a couple of times：

/usr/include/c++/7/debug/safe_unordered_container.h(71): error: a nonstatic member reference must be relative to a specific object

Any idea on how to debug this error? Many thanks!
