Hi, >> cmake /path/to/vpp/src [your favorite xcompile args] cmake —build . Instead of having a shell script to pass cmake commands, I really liked the idea of passing vpp_cmake_args from build-data/platforms/*.mk (https://gerrit.fd.io/r/#/c/vpp/+/21035/23/build-data/platforms/native.mk@42). Any comment of taking those changes?
