C++ CMake can'；在windows中找不到opencv

我已在windows中安装OpenCV（源代码）

现在我想尝试一个测试，所以我有以下CMakeLists.txt

cmake_minimum_required(VERSION 3.0.0)
project(opencvGPUtest_youtube VERSION 0.1.0)

include(CTest)
enable_testing()

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

add_executable(opencvGPUtest_youtube main.cpp)

target_link_libraries(opencvGPUtest_youtube ${OpenCV_LIBS})

set(CPACK_PROJECT_NAME ${PROJECT_NAME})
set(CPACK_PROJECT_VERSION ${PROJECT_VERSION})
include(CPack)

然而，当我做。。从我得到的一个构建文件夹

CMake Error at CMakeLists.txt:13 (find_package):
  By not providing "FindOpenCV.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "OpenCV", but
  CMake did not find one.

  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.

我已尝试编辑CMakeLists.txt文件，以包括Opencv目录，如中所示

find_package(OpenCV REQUIRED PATH C:/Users/theuser/Path/To/MyOpenCVInstallation/build/install/x64/vc16/lib

或

但它仍然找不到OpenCV

我还尝试了-DOpenCV_DIR选项，但没有结果

如何使其识别OpenCV

编辑：

当我将OpenCV_DIR指定为myoppencvinstallation/build/install/x64/vc16/lib时，错误变为

CMake Error at C:/Program Files/CMake/share/cmake-3.20/Modules/FindPackageHandleStandardArgs.cmake:230 (message):
  Could NOT find OpenCV (missing: PATH
  C:/Users/user/Path/To/MyOpenCVInstallation/build/install/) (found
  version "4.5.2")
Call Stack (most recent call first):
  C:/Program Files/CMake/share/cmake-3.20/Modules/FindPackageHandleStandardArgs.cmake:594 (_FPHSA_FAILURE_MESSAGE)
  C:/Users/user/path/to/MyOpenCVInstallation/build/install/x64/vc16/lib/OpenCVConfig.cmake:410 (find_package_handle_standard_args)
  CMakeLists.txt:13 (find_package)

编辑2：

结果我不得不使用

find_package(OpenCV REQUIRED PATHS C:/Users/theuser/Path/To/MyOpenCVInstallation/build/install/x64/vc16/lib

这样看来，cmake运行正常

然而，通常在这一点上（在ubuntu中），我运行

make

，但在windows中，我应该使用VSCode中的CtrlF5

现在我得到了输出

因此，我认为这是一个不同的问题？

那么，在您的OpenCV安装下，文件

OpenCVConfig.cmake

的确切路径是什么？将目录与该文件一起用作

OpenCV\u DIR

变量的值。我搜索了

OpenCVConfig.cmake

，得到了四（4）个文件。路径是：C:..\myOpenInstallation\build\win install\x64\vc16\lib，然后是另一个带有install\x64\vc16\lib的路径，另外两个路径正好是win install或install。我应该使用哪一个可能是安装文件夹中的一个，但在任何情况下都可能有效。CMake将使用生成文件夹或安装文件夹中的包。我通常不构建安装目标，而是使用构建文件夹。根据软件包的不同，安装可能有一个优点，即头可以组合在一个文件夹中，而不是分散在一个文件夹中。安装没有这样的

PATH

选项。您可能指的是

路径

选项。但由于您已指定了

OpenCV_DIR

变量，因此不需要该选项。错误代码

0xc0000135

表示您的某些dll库未列在

路径

环境变量中。见例。
