DPDK headers are incompatible with MSVC due to heavy use of extensions common to GCC, clang, and ICC. DPDK libraries can be linked trivially. If your app cannot be easily recompiled with clang, I think the best way is to use two compilers: compile the module that interfaces DPDK with clang and the rest of the app with MSVC, link DPDK libraries as any other external libraries. Note that DPDK installation on Windows is not fully functional yet: it does not install pthread.h which you can find in lib/eal/windows/include= . +Tyler who might have relevant experience.
