In digging into this, it makes sense. OpenEXR doesn't even provide a library named OpenEXR, instead:

$ dnf repoquery --provides OpenEXR-libs
...
libIlmImf-2_3.so.24
libIlmImf-2_3.so.24()(64bit)
libIlmImfUtil-2_3.so.24
libIlmImfUtil-2_3.so.24()(64bit)

And strangely ilmbase provides mostly libraries that don't contain ilm!

$ dnf repoquery --provides ilmbase
...
libHalf.so.24
libHalf.so.24()(64bit)
libIex-2_3.so.24
libIex-2_3.so.24()(64bit)
libIexMath-2_3.so.24
libIexMath-2_3.so.24()(64bit)
libIlmThread-2_3.so.24
libIlmThread-2_3.so.24()(64bit)
libImath-2_3.so.24
libImath-2_3.so.24()(64bit)

And ALL of the headers for both packages get installed into /usr/include/OpenEXR!

So here's my plan:

1. Repackage openexr from scratch including review request (Rex?)

1a. Include appropriate Provides/Obsoletes for current OpenEXR and ilmbase packages

2. Perform all testing and dependent rebuilds in a COPR first.

3. Build openexr and dependencies in a side-tag

4. Merge the side tag and retire OpenEXR and ilmbase

So what am I forgetting? Thoughts?

Thanks,
