Installing further development packages

This is a great project.

I was wondering what the recommended approach would be for adding a common package to all of the images for a specific setup.

e.g. in my situation, I need prebuildify docker images which include libudev-dev.

I can see two approaches, both with drawbacks:

• Derive our own docker images adding this package. This approach requires maintenance of each derived image (current count is 7). I've also found this works in some cases, but I've had issues with the arm based images and the package still isn't found when using:

FROM gchr.io/prebuild/linux-armv6:1
USER 0
RUN apt-get -y update && apt-get -y install libudev-dev
USER node

• Use a prebuildify preinstall command to install the package. This doesn't feel right architecturally, but is easier to maintain without derived docker images. This approach also fails because sudo isn't allowed.

Solved using derived images which copy the lib files to the proper cross-compiled locations. e.g.:

FROM ghcr.io/prebuild/android-arm64:1
USER 0
COPY arm64/libudev.h ${QEMU_LD_PREFIX}/usr/include/
COPY arm64/libudev.so ${QEMU_LD_PREFIX}/usr/lib/
USER node
