Dependencies latest Actions -- Fix OpenImageIO install on Windows

[doug-walker]

This issue is to solve the issue that is causing the GitHub Actions Dependencies Latest CI runs to fail due to a problem installing OpenImageIO on Windows.

It seems that latest OpenImageIO versions require OpenColorIO to build, which mean we have a circular dependency. Should we drop building OIIO from the dependencies latest workflow?

[zachlewis]

Is it causing problems? I know when OIIO uses a custom namespace when building OCIO...

[remia]

Maybe we just need to enable -DOpenImageIO_BUILD_MISSING_DEPS=all then?

[zachlewis]

That would definitely do the trick.

@remia , should this be closed?

[remia]

We can close it I think so yes, but noting that the update just disable OIIO builds from the dependencies latest workflow now that OIIO has a mandatory dependency on OCIO. We could try to ask OIIO itself to build OCIO internally before rebuilding it ourselves later but that seems a bit convoluted. Anyway this can be addressed separately if we feel like it would be important to add back.
