无法将 OpenCV 中的 .dll 与 CMake 一起使用
Cannot use .dll from OpenCV with CMake
我有以下CMakeLists.txt
cmake_minimum_required(VERSION 3.12)
project( project_360_visual )
find_package( OpenCV REQUIRED )
set(SOURCE_FILES
${CMAKE_SOURCE_DIR}/src/project_360_visual.cpp
${CMAKE_SOURCE_DIR}/src/projection.cpp)
set(INCLUDE_FILES
${CMAKE_SOURCE_DIR}/include/project_360_visual.h
${CMAKE_SOURCE_DIR}/include/projection.h)
LINK_DIRECTORIES(c:/opencv/build/bin/Release)
add_library(opencv_tracking430 SHARED IMPORTED GLOBAL)
set_target_properties(opencv_tracking430 PROPERTIES IMPORTED_LOCATION c:/opencv/build/bin/Release/opencv_tracking430.dll)
add_executable( project_360_visual ${SOURCE_FILES} ${INCLUDE_FILES})
target_include_directories(project_360_visual PUBLIC ${CMAKE_SOURCE_DIR}/include)
target_link_libraries( project_360_visual PUBLIC ${OpenCV_LIBS} opencv_tracking430)
相关的 Visual Studio 项目是使用以下方法生成的：
cmake ../ -G "Visual Studio 15 2017 Win64" -DCMAKE_PREFIX_PATH=c:/opencv/build
但是，无论我做什么，我都无法link/import 正确地管理 OpenCV 中的共享库。有人可以帮我解决这个问题吗？
这是我尝试构建时 Visual Studio 的当前输出：

这可以编译，但是在 运行 时它抱怨找不到相关的 .dll：

您不link 反对 DLL 库。这些文件用于 运行-time 加载器。通常，DLL 将与 .lib 导入库配对，您 可以 将其用于 linking。针对具有配对 .lib 的 DLL 导入和 link 的 CMake 语法如下（也使用 IMPORTED_IMPLIB）：
add_library(opencv_tracking430 SHARED IMPORTED GLOBAL)
set_target_properties(opencv_tracking430 PROPERTIES IMPORTED_LOCATION
c:/opencv/build/bin/Release/opencv_tracking430.dll
