@NoWineNoLife, sorry I can't reproduce your error:

CMakeLists:

cmake_minimum_required(VERSION 3.5)

project(test)

find_package(OpenCV CONFIG REQUIRED)

add_executable(test CMakeProject1.cpp)
target_link_libraries(test PRIVATE opencv_ml opencv_dnn opencv_dpm opencv_hdf)

Are you using the latest vcpkg? What is your opcncv version?

[dg0yt]

set(CMAKE_TOOLCHAIN_FILE "D:/develop_kits/vcpkg/scripts/buildsystems/vcpkg.cmake")
project(test LANGUAGES CXX)

set(CMAKE_PREFIX_PATH "D:/develop_kits/vcpkg/installed/x64-windows/share/")

The last line overwrites toolchain configuration (and also potential user input). You may append or prepend if you want. But for vcpkg, it shouldn't be needed at all.

Hi, @JonLiu1993 , in my env, the vcpkg version is 2024-03-14-7d353e, the opencv version is 4.8.0

[NoWineNoLife]

@dg0yt Thanks for pointing that out.

[dg0yt]

@dg0yt Thanks for pointing that out.

So is your issue resolved now?

[NoWineNoLife]

@dg0yt unfortunately, no. i downloaded the opencv library from opencv.org and set it manually.

So did you try to fix your CMakeLists.txt and start with a fresh build directory? CMake's caching requires to clean the cached variables in some cases,
