* Tune the meson build option pointing the location of the FlexRAN SDK libraries ``flexran_sdk``
* Point pkgconfig towards these libraries so that they can be automatically found by meson.
If not, DPDK will still compile but the related functionality would be stubbed out.

* For AVX512 machines with SDK libraries installed then both 4G and 5G can be enabled for full real time FEC capability.
For AVX2 machines it is possible to only enable the 4G libraries and the PMD capabilities will be limited to 4G FEC.
