[dpdk-dev] [PATCH 3/6] net/mlx: fix meson build with custom dependency path

[Thomas Monjalon <thomas@monjalon.net>]

If rdma-core is not installed in a standard directory of the system,
it is possible to specify the location of the pkgconfig file via
an environment variable:
PKG_CONFIG_PATH=$PKG_CONFIG_PATH:~/rdma-core/build/lib/pkgconfig

In this case, the dependency may become mandatory to specify
for the configuration tests (checking dependency symbols or fields).

Some spacing is also fixed around.

Fixes: 8e4937640022 ("net/mlx4: add external allocator for Verbs object")
Fixes: 1dd7c7e38c19 ("net/mlx4: support meson build")
Fixes: 96d7c62a70c7 ("net/mlx5: support meson build")
