Yes.
Each example exposes its required dependencies.
examples/meson.build will skip any example with unmet requirements
unless the example was explicitly set in the -Dexamples= list of
examples to build.

See:
https://git.dpdk.org/dpdk/tree/examples/meson.build#n105

https://git.dpdk.org/dpdk/tree/examples/meson.build#n79

I already tested this series with our script: we already have a "mini" target.

build build-mini cc skipABI $use_shared -Ddisable_libs=* \
        -Denable_drivers=net/null
