I have not built anything with mlx in a long time. My guess is the libmix4.so.1 is not located in a place the system can pick up. Maybe you need to set LD_LIBRARY_PATH to the path where this library is located. I see you included the DPDK PMD, but you still need to tell applications where to locate the library. Another option is to add it to the /etc/ld.so.conf.d/ file or use pkg-config to locate the libs may help too. In some cases external packages do not store the libs in a standard place for ldconfig to locate or the package does not provide ldconfig configuration files.
