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) and builds the same without it. I found out while solving linked problem, but in your case it is not applicable.
Hello, any update regarding this issue?
This bug appears to have been reported against 'rawhide' during the Fedora 28 development cycle. Changing version to '28'.
Orphaned package
