You are probably using an old version of docker that doesn't have buildkit enabled by default. You can try to add DOCKER_BUILDKIT=1 in front of your docker build command

[Corallo]

Also, to avoid further problems, update your firmware to the latest version. The 1.5 version of the sdk have a breaking change. It won't work with fw lower than 11.0
