[question] ffmpeg/6.1 : try to build with CUVID support

[narcdev]

What is your question?

I'm currently trying to build the latest version of FFMPEG with CUVID support. It work well with FFMPEG 4.4, but with the latest version I've the following error message :

LINK : fatal error LNK1181: cannot open input file 'lzma.lib'

It only appears when I set CUVID support.

Conan version 1.63.0 or 2.3.1, it is the same error message.

Conan 2.3.1 profile :

[settings]
arch=x86_64
build_type=Release
compiler=msvc
compiler.cppstd=14
compiler.runtime=dynamic
compiler.version=192
os=Windows
