Rather than trying to build DPDK with g++, or to use the DPDK makefiles
with your C++ application, can I recommend instead that you treat DPDK as
any third-party library and build it independently of your application.

If you compile and install DPDK using meson and ninja - or install the
DPDK package from your linux distro - you will have a 'libdpdk.pc' file
installed for use by pkg-config. Then for building your application, put in
the relevant calls to pkg-config i.e. 'pkg-config --cflags libdpdk' and
'pkg-config --libs libdpdk', into your app makefile and work from there.

Note too, that all DPDK header files should already be safe for inclusion
in C++ code - if not, please log a bug.
