如何在 Linux 中为我的 C++ 程序编写一个简单的 OpenViNO CMAKELISTS
How to write a simple CMAKELISTS for OpenViNO to my C++ programme in Linux
我一直在努力为我的 C++ 程序设置 OpenVINO。但是 official guide 对我来说非常不清楚（部分原因是我是一个非常初学者）。我一直在努力理解它是如何在没有定义它的情况下找到“InferenceEngine_LIBRARIES”（或“OpenCV_LIBS”）的。
我试图理解 GitHub 中的一些示例，但遗憾的是，其中许多是针对旧版本的。我想知道我是否可以获得 CMakeLists.txt 的最低演示以使用 OpenVINO。非常感谢。

感谢您的评论。我知道有些事情是由 CMake 在幕后处理的。进入正题，这是我的 CMakeLists 文件
cmake_minimum_required(VERSION 3.21)
project(openvino)
set(CMAKE_CXX_STANDARD 14)
# OpenVINO
set(ngraph_DIR "/opt/intel/openvino_2021/deployment_tools/ngraph/cmake")
find_package(ngraph REQUIRED)
set(InferenceEngine_DIR "/opt/intel/openvino_2021/deployment_tools/inference_engine/share")
find_package(InferenceEngine REQUIRED)
set(OpenCV_DIR "/opt/intel/openvino_2021/opencv/cmake")
find_package(OpenCV REQUIRED)
add_executable(openvino main.cpp)
target_link_libraries(
${PROJECT_NAME}
PRIVATE ${InferenceEngine_LIBRARIES}
${OpenCV_LIBS}
${NGRAPH_LIBRARIES})
而我的“main.cpp”只是
#include <inference_engine.hpp>
int main() {
InferenceEngine::Core core;
InferenceEngine::ExecutableNetwork executable_network;
executable_network = core.LoadNetwork("./models/decoder.xml", "CPU");
auto infer_request = executable_network.CreateInferRequest();
return 0;
}
但是当我构建它时，出现了以下错误，我想寻求任何帮助。非常感谢！

链接器错误显示它找不到 TBB 符号。 TBB_DIR 变量应指向 TBB 库。您不必使用 cmake 的 set() 函数手动设置这些变量。相反 - 在您编译自己的应用程序的 shell 中 - 您可以获取 OpenVINO 的 setupvars.sh 脚本。只是 运行 类似的东西：source /opt/intel/openvino_2021/bin/setupvars.sh 和 re-run 编译器。
我可以看到您正在使用 CLion，而不是直接使用终端。在这种情况下，您可以尝试手动添加变量。 OV 版本之间的 TBB 位置可能略有不同，但通常它应该指向 /opt/intel/openvino_2021 的子目录 - 只需浏览安装目录并尝试在终端中找到它或来源 setupvars.sh 并复制TBB_DIR 您的 IDE.
