Firstly, I'm a little unclear on your exact use case. Just to be really clear, are you using cmake within a bitbake build or are we talking about using cmake from within an SDK or eSDK external to the project? I'm guessing this is probably an SDK question but you never mention the SDK anywhere so I wasn't entirely sure. I'll assume that in my next comment. With the SDK, if you have two projects, one of which depends on the other, I have to wonder where the first is being installed to? Usually I'd have expected it to go into the target sysroot that the SDK toolchain is using, then it should be found by the second build? We don't support multiple sysroots for building things with the SDK. I'm therefore still a bit puzzled about exactly what the issue is here so perhaps you could give a little more detail on the above? Cheers, Richard
