Houdini 20 support

[crystalthoughts]

Hi, is there a build process for updating to newer Houdini versions or is it more involved than that?
Would be great to have a Houdini 20 build :)
Thanks

Also looking for h20 verison, or updated docs on how to build. Configured cmake to account for py3.10 but couldn't get it to build and don't have the skills to figure out why
Cheers
