Can you tell me how to fix it? Thanks.

FWIW this tap doesnt manage the bladerf recipe. It looks to be an cmake typo that was acceptable to older cmake versions. I think they fixed it upstream, but I dont see a new brew release tag for this; so maybe the best thing to do is install libbladerf from HEAD.

thanks,i'll try it as you say.

not much I can do, hope that worked out
