in make step I meet a error with main.cpp

[jackft2]

my CmakeList : cmake_minimum_required(VERSION 3.0 FATAL_ERROR) project(yolo-app)

find_package( OpenCV 3.4.9 REQUIRED ) include_directories( ${OpenCV_INCLUDE_DIRS} ) message(${OpenCV_INCLUDE_DIRS})

find_package(Torch REQUIRED)

aux_source_directory(. DIR_SRCS)

add_executable(yolo-app ${DIR_SRCS}) target_link_libraries(yolo-app "${TORCH_LIBRARIES}" "${OpenCV_LIBS}") set_property(TARGET yolo-app PROPERTY CXX_STANDARD 11)

my terminal show that:
