Hi Luca, Thanks so much for the reply. My issue turned out to have nothing to do with cmake or loading external libraries, but reviewing your gr-dab module was greatly helpful in that I was able to compare what I was doing against a known working example, so thank you for that.  This led me to

Hi William, I am not sure, if this is your issue, but it seems as your external lib is not found by your cmake. I currently dealt with including some external libraries in the gr-dab module too. I always wrote a Find.cmake file that lets cmake find the path to your library header. Check

Hi Sebastian, this is certainly the right place to come and ask :) So, thank's for the error description. I'm pretty optimistic this isn't your code's problem – there's something else amiss. If you go down the backtrace, you'll notice that this happens (or at least, seems to happen) inside the
