c++ - CMake在Windows中找不到opencv

问题描述

我已经在 Windows 中安装了 OpenCV（来自源代码）

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)

但是，当我从我得到的构建文件夹中执行 cmake ..

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.

我尝试编辑 CMakeLists.txt 文件以包含 Opencv 的目录，如

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

或者

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

但它仍然找不到 OpenCV

我也试过 -DOpenCV_DIR 选项，没有结果

如何让它识别 OpenCV？

编辑：

当我将 OpenCV_DIR 指定为 MyOpenCVInstallation/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：

原来我不得不使用

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

有了这个，cmake似乎没问题。

但是通常此时（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

The program '[1112] opencvGPUtest_youtube.exe' has exited with code -1073741515 (0xc0000135).

所以我想这是一个不同的问题？
