ERROR: cuvid requested, but not all dependencies are satisfied: ffnvcodec

Im running this script on a brand new ubuntu 22 install and get the following error

ERROR: cuvid requested, but not all dependencies are satisfied: ffnvcodec

Same as #183

Changing
--disable-ffnvcodec
to
--enable-ffnvcodec
in the script "build-ffmpeg" temporarily solves the issue and allows it to compile

--disable-ffnvcodec
is supposed to result in ffmpeg autodetecting the presence of the headers, but this for some reason isn't working, even when they are present system-wide or in the include directories. I've not gone further into finding out why yet.

Thanks, this worked for me but I also had to modify my path and add the following since I'm building the nv-codec-headers under the HWaccel library section.

Here's my git diff that let's me successfully build:

I also set line 932 to --enable-ffnvcodec but that wasn't enough. After some searching I tried this and it worked...

cd packages/nv-codec-headers-11.1.5.2/
make install PREFIX=~/ffmpeg-build-script/workspace/usr
