Let me try and summarize, DPDK has replaced a flag that used to point to the binary with a static/non-static flag and is using pkg-config to locate the binary. If the yocto dpdk package isn't producing a valid set of .pc files that pkg-config is looking for, then it won't find them and that doesn't help us. So we need to see if the dpdk package is producing them, and if so, why aren't they in the right place. If we don't want to go that route, did you try setting the DPDK_CFLAGS and DPDK_LIBS to the path to where the libraries have been installed in the package sysroot ?
