cmake: use of imported Freetype target

[nilason]

Use imported Freetype target.

I have a question. What happens if we select WITH_FREETYPE=off, does g.mkfontcap and v.label.sa compile as expected? Here there's no usage of PRIMARY_DEPENDS like in the other PRs. Is this because the headers are conditionally included (include guard), and cmake imported targets don't fail when they don't exist?

Thanks, good point! It is my understanding that none of the two would work without Freetype, added PRIMARY_DEPENDS.

I didn't dive into the source, do they work without? Does configuring work without too?

As far as I can tell, they do not work without. As "ordinary" DEPENDSs they would silently not build, whereas with PRIMARY_DEPENDS there is a message in configure, which can be good to know.
