There should not be any reason to have the ilmbase package as separate one, because this package has been incorporated into the openexr package itself (in version 3).
As per libHalf, this functionality has been moved into a new package imath, that was introduced by upstream with release of openexr 3 and is available in Fedora now.
Unfortunately, building OpenColorIO 2.0 failed to properly detect libHalf despite the inclusion of imath.
Extract below:

It looks like my official build built fine with Imath...
So that problem is solved. Now I'm working on blender. I see there is a patch for OpenEXR3 that isn't applied. I assume it is no longer necessary?
I found the issue with the types. Int64 and Sint64 are well, the porting guide says deprecated but as the build fails, I would call that obsolete, in favor of standard types int64_t and uint64_t.
Thanks,
Richard
