使用vcpkg+cmake+opencv生成项目，却遇到 fatal error: “opencv2/core/core.hpp”: No such file or directory

Question

我使用 VCPKG 下载 OpencV：

./vcpkg install opencv2:x64-windows

Computing installation plan...
The following packages are already installed:
    opencv2[core,eigen,jpeg,png,tiff]:x64-windows -> 2.4.13.7#5
Package opencv2:x64-windows is already installed

Total elapsed time: 2.225 ms

The package opencv2:x64-windows provides CMake targets:

    find_package(OpenCV CONFIG REQUIRED)
    # Note: 15 target(s) were omitted.
    target_link_libraries(main PRIVATE opencv_ml opencv_ts opencv_gpu opencv_ocl)

并像这样编写 cmakelists：

cmake_minimum_required(VERSION 3.10) 

set(CMAKE_TOOLCHAIN_FILE E:/vcpkg/scripts/buildsystems/vcpkg.cmake
  CACHE STRING "Vcpkg toolchain file")

# set the project name 
project(QRCODE)
# add the executable 
add_executable(qrcode main.cpp)

find_package(OpenCV COMPONENTS REQUIRED)
# Additional Include Directories
include_directories( ${OpenCV_INCLUDE_DIRS} )

# Additional Library Directories
link_directories( ${OpenCV_LIB_DIR} )

# Additional Dependencies
target_link_libraries(qrcode ${OpenCV_LIBS})

message("${OpenCV_DIR}")
message("${OpenCV_INCLUDE_DIRS}")

令我困惑的是 cmake 输出如下所示：

E:/vcpkg/installed/x64-windows/share/opencv
/include/opencv;/include

似乎 opencv 没有安装成功，或者 cmake 找不到 opencv 安装路径。 当我使用cmake工具构建项目时，遇到致命错误：“opencv2/core/core.hpp”：没有这样的文件或目录。
