The parameters for compiling and linking against DPDK (DPDK_CFLAGS
and DPDK_LDFLAGS or DPDK_INCLUDE_DIRS, DPDK_LIBRARIES and
DPDK_LIBRARY_DIRS) are not trivial to determine and can be best
provided by pkg-config. Therefore, use pkg-config to find DPDK and
do not allow user provided DPDK variables.
To compile UHD against DPDK which was installed to a custom prefix,
e.g. /opt/dpdk-22.11, provide this path as parameter
CMAKE_PREFIX_PATH:
cmake .. -DCMAKE_PREFIX_PATH=/opt/dpdk-22.11
