如何在Linux中為我的C 程式撰寫一個簡單的OpenViNOCMAKELISTS-有解無憂

我一直在努力為我的 C 程式設定 OpenVINO。但是官方指南對我來說非常不清楚（部分是因為我是一個非常初學者）。我很難理解它是如何找到“InferenceEngine_LIBRARIES”（或“OpenCV_LIBS”）的，甚至沒有定義它。

我試圖理解 GitHub 中的一些示例，但遺憾的是其中許多是針對舊版本的。我想知道是否可以有一個 CMakeLists.txt 的最小演示來使用 OpenVINO。非常感謝你。

感謝您的評論。我知道有些事情是由 CMake 在幕后處理的。說到重點，這是我的 CMakeLists 檔案

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;
}

但是當我構建它時，我得到了以下錯誤，我想尋求任何幫助。非常感謝你！

uj5u.com熱心網友回復：

聯結器錯誤表明它找不到 TBB 符號。TBB 庫應由 TBB_DIR 變數指向。您不必使用 cmake 的 set() 函式手動設定這些變數。相反 - 在您編譯自己的應用程式的 shell 中 - 您可以獲取 OpenVINO 的 setupvars.sh 腳本。只需運行類似：source /opt/intel/openvino_2021/bin/setupvars.sh并重新運行編譯器。我可以看到您使用的是 CLion，而不是直接使用終端。在這種情況下，您可以嘗試手動添加變數。OV 版本之間的 TBB 位置可能略有不同，但通常它應該指向的子目錄/opt/intel/openvino_2021- 只需瀏覽安裝目錄并嘗試在終端中找到它或 source setupvars.sh 并將 TBB_DIR env var 值復制到您的 IDE .
