Re: [yocto] INCOMPATIBLE_LICENSE - how to use it properly?

["John Ernberg" <john.ernberg@actia.se>]

Hi Alex,

I will give this a try on master.

One question though, will this still catch build-only libraries? (i.e. a 
library that consists only of headers). I don't think we have such 
recipes right now, it's more to understand how this feature works.

Thank you.

Best regards // John Ernberg
