It was supported with make build system in commit 2c0dd7b69fb0 ("config: add static linkage of mlx dependency"). The same feature is enabled with meson when using pkg-config (i.e. only if the call to dependency() is successful). The fallback method for searching library with cc.find_library() is not supported because the dependencies of the found library would not be linked (no such info in .a file unlike .so). The main difference, in meson build system, is the generated .pc file giving arguments to link DPDK with the application. Unfortunately the .pc file will not keep memory of the static linkage option for libibverbs.
