- did you install freetype and harfbuzz dependancies ?
- yes, you need
WITH_FREETYPE=ON
- please show the complete cmake console output (rather long, but it has hints)
- make sure, you use exactly the same version for both opencv main and contrib repos (if you want to use 4.5.2, check out the 4.5.2 branch in contrib, too !)
- please also see the related answer here
