For any project using bazel, if we want to use DPDK, then we need to compile DPDK stuff into bazel by ourselves. It is not a trivial thing and the bazelment (https://github.com/bazelment/dpdk) guys have spent much effort extracting the core files in DPDK and write the BUILD files for DPDK. But now it seems they have stopped maintaining that repo since DPDK 16.04. Even in that version, it has some runtime failure when we use DPDK in our bazel project.

Why is it too bad?
How the choice of an internal build system
can affect other projects?

Why the DPDK community would support building with Bazel?
What is the benefit?
Bazel projects cannot just link with DPDK using pkg-config?

After all, writing the bazel files can be really challenging, especially if we do not have a very deep understanding of the whole DPDK codes.

DPDK supports library standards for compiling, installing and linking.
What else is needed?
