so to add hdr10 ability, I have to add -DHIGH_BIT_DEPTH:bool=on to the cmake section of x265.
is this in place of or along with the -DENABLE_SHARED:bool=off instruction
sorry I am a new to this and want to continue with Linux and this has been a major headache trying to get the hdr10 opt available in x265.
only found this page the other day and has helped lots.

I'm getting some error like this.
How to resolve it? Thx...

If you think configure made a mistake, make sure you are using the latest
version from Git. If the latest version fails, report the problem to the
[email protected] mailing list or IRC #ffmpeg on irc.libera.chat.
Include the log file "ffbuild/config.log" produced by configure as this will help
solve the problem.
