在Windows上使用Vcpkg安裝OpenCV

0、準備工作：

安裝Git，建議勾選Git-LFS
安裝CMake
安裝visual studio 2019英文版      

1、拉取vcpkg代碼

$ git clone https://github.com/microsoft/vcpkg.git      

2、初始化vcpkg

$ ./bootstrap-vcpkg.bat      

3、檢視目前OpenCV版本，可以看到我本機上預設opencv是4.6.0版本，opencv3是3.4.18版本

$ ./vcpkg.exe search opencv

If you do not install the meta-port *opencv*, the package opencv4 is compatible with CMake
if you set the OpenCV_DIR *before* the find_package call

    set(OpenCV_DIR "D:/Projects/vcpkg/installed/x64-windows/share/opencv4")
    find_package(OpenCV REQUIRED)      

set(OpenCV_DIR "D:/Projects/vcpkg/installed/x64-windows/share/opencv4")
find_package(OpenCV REQUIRED)
