I encountered this on x64-linux.

Was changed in #18839, but should work. Has the port the dependency to vcpkg-cmake?

[autoantwort]

I don't know classic mode that much, but maybe an old version of vcpkg-cmake was already installed, but ffmpeg needs the updated version of vcpkg-cmake. So maybe do a vcpkg upgrade

[Be-ing]

vcpkg upgrade fixed it, thanks.

[Be-ing]

I think the ffmpeg port should specify a minimum version for vcpkg-cmake?

[autoantwort]

I think the ffmpeg port should specify a minimum version for vcpkg-cmake?

Seems that this is not possible

[JackBoosY]

Unknown CMake command "vcpkg_cmake_get_vars".

Please pull the latest code and bootstrap again.

[JackBoosY]

Solved.

[Hoikas]

Solved in which commit?

@Hoikas This: #19260 (comment)

The reason why vcpkg_cmake_get_vars wasn't find is because vcpkg-cmake has been upgraded.
So please remove vcpkg_cmake and install it again.
