net/mlx4: support meson build
Compile Mellanox driver when their external dependencies are met. A glue version of the driver can still be requested by using the -Denable_driver_mlx_glue=true Meson will try to find the required external libraries. When they are not installed system wide, they can be provided though CFLAGS, LDFLAGS and LD_LIBRARY_PATH environment variables, example (considering RDMA-Core is installed in /tmp/rdma-core): # CLFAGS=-I/tmp/rdma-core/build/include \ LDFLAGS=-L/tmp/rdma-core/build/lib \ LD_LIBRARY_PATH=/tmp/rdma-core/build/lib \ meson output # LD_LIBRARY_PATH=/tmp/rdma-core/build/lib \ ninja -C output install Note: LD_LIBRARY_PATH before ninja is necessary when the meson configuration has changed (e.g. meson configure has been called), in such situation the LD_LIBRARY_PATH is necessary to invoke the autoconfiguration script.
