Hello, I'd like you to ask to remove any mysql-devel / mariadb-devel BuildRequires form your package SPECfile. The package does not use it in any way (or atleast as far as I checked). I found out while solving linked problem, but in your case it is not applicable.
Hello, any update regarding this issue?
I re-enabled mysql and postgresql support in vtk and used the new mariadb BR for F28+.
