[github-actions]

You have modified or added at least one portfile where deprecated functions are used.

If you feel able to do so, please consider migrating them to the new functions:
vcpkg_install_cmake -> vcpkg_cmake_install (from port vcpkg-cmake)
vcpkg_build_cmake -> vcpkg_cmake_build (from port vcpkg-cmake)
vcpkg_configure_cmake -> vcpkg_cmake_configure (Please remove the option PREFER_NINJA) (from port vcpkg-cmake)
vcpkg_fixup_cmake_targets -> vcpkg_cmake_config_fixup (from port vcpkg-cmake-config)

In the ports that use the new function, you have to add the corresponding dependencies:

{
  "name": "vcpkg-cmake",
  "host": true
},
{
  "name": "vcpkg-cmake-config",
  "host": true
}

The following files are affected:

• ports/darknet/portfile.cmake

You have modified or added at least one vcpkg.json where a "license" field is missing.

If you feel able to do so, please consider adding a "license" field to the following files:

• ports/darknet/vcpkg.json

Valid values for the license field can be found in the documentation

Can you check if darknet's opencv* dependencies really need the default features of opencv*?
ATM darknet[opencv*] prevents opting out from default features of opencv. Cf. #20471 (comment).

@cenit ,Thanks for your pr, When I run the comand "./vcpkg install darknet[*]:x64-windows" tested the features locally, It failed :

CMake Error at ports/opencv2/portfile.cmake:6 (message):
  OpenCV 4 is installed, please uninstall and try again:

      vcpkg remove opencv4
Call Stack (most recent call first):
  scripts/ports.cmake:145 (include)


error: building opencv2:x64-windows failed with: BUILD_FAILED
Please ensure you're using the latest portfiles with `git pull` and `.\vcpkg update`.
Then check for known issues at:

Then I ran the command "./vcpkg remove opencv4:x64-windows" to remove the opencv4 port and tried the command "./vcpkg install darknet[*]:x64-windows" again, but still got this error

[cenit]

yes, darknet is one of the very few ports that do not obey to new rules, meaning that there are features mutually exclusive and not additive.
In fact, if you use opencv-base, you cannot ask for opencv2-base or opencv3-base, because the opencv version on which they depend are incompatible between themselves

Tested fearture [cuda,cudnn,full,opencv-base,opencv-cuda] successfully in the x64-windows triplet
