[jakirkham]

Many RAPIDS projects have started making use of devcontainers for project development

This leverages a container to spin up a fully functional development environment to work in

As an example, here is how RMM uses devcontainers

We might consider doing the same thing with cuCIM

This may also obviate existing development solutions like our VSCode setup ( #706 )

It may also pair well with other work like devendoring CMake dependencies ( #686 ) and using rapids-cmake ( #627 )
