Please just copy/paste the error text into your question (use the Preformatted text button (the one with 101010 on it)), don't use images to show us what is essentially text.

Also: please use a more descriptive question title "ask for help" doesn't tell us much.

why??!!! the picture is clear

One important reason: images are not searchable by search engines, so people can't use the search to find it. It's also impossible to quote parts of your image. Additionally (but it is not the case here): image hosters have different retention periods, which might lead to lost images.

A bit of a guess, as you haven't included your CMakeLists.txt, but it appears that you're trying to add_dependencies(range ..) while there is no target range declared anywhere.

That is essentially what the error is telling you.

so, what can i do please?

Figure out where the add_dependencies(..) is, and why it's referring to a target called range. Then also figure out why that target doesn't exist. Or something similar.
