System freetype not detected?

When I set Lutris WINE runner to prefer system libraries wine complains about freetype (informs it is not installed) and thus I don’t get text in Battle.net launcher for example.
I’m pretty sure I have it (version 2.9.1, both 64 and 32 bit, running on OpenSUSE Leap 15).
Any ideas why it behaves this way? Is it fixable?
