CMakelist:
#cmake版本
cmake_minimum_required(VERSION 3.10)
#项目文件夹名称
project(Choose_Connected)
find_package(CUDA REQUIRED)
find_package(OpenCV REQUIRED)
#查找当前目录下的所有源文件，并将名称保存到 DIR_SRCS 变量
aux_source_directory(. DIR_SRCS)
INCLUDE_DIRECTORIES(/usr/local/cuda-10/include)# 指定CUDA头文件的搜索路径
list(APPEND CUDA_NVCC_FLAGS "-std=c++11")# 使CUDA NVCC 编译器支持C++11特性
cuda_add_executable(${PROJECT_NAME} Connected_Choose_4.cpp)#构建可执行目标文件所需要的源文件
target_link_libraries(opencv ${OpenCV_LIBS})
问题1：
Could not find a package configuration file provided by “OpenCV” with any
of the following names:
OpenCVConfig.cmake opencv-config.cmake
Add the installation prefix of “OpenCV” to CMAKE_PREFIX_PATH or set
“OpenCV_DIR” to a directory containing one of the above files. If “OpenCV”
provides a separate development package or SDK, be sure it has been
installed.

注意：你用的博客中方法2，而且方法2中的你TX2中的路径是: /home/nvidia/myopencv/build/(好像是这个，主要要有OpenCVConfig.cmake或者opencv-config.cmake)
问题2：你哪怕编译一个简单的cpp程序就会报你程序中有不认识的符号，如不认识include中的“i”是啥等，就感觉语法识别有问题
