Yes, there is a gotcha though wrt the question asked. Using `build-packages`, which install on the host -the usual `-dev` ones- means that the libraries they bring in need to be added as `stage-packages`. We added an optimization here where we crawl all elf files in `prime` and `ldd` them to see if anything would resolve outside the snap and bring those libraries in. This is not as easy with classic confinement as all those elf files are runpathed. I have slept on it though and think there is a way to do it, but it won't be as straightforward.
