  If MLNX_OFED is installed, there's no .pc file installed for libraries and
dependency() can't find libraries by pkg-config. By adding fallback of
using cc.find_library(), libraries are properly located.

Minor suggestion - you can reduce the size of the diff in this patch by
defining the first array as "libnames" and keeping the actual dependency
objects as "libs".

Doesn't this end up trying to link the test program to -llibmnl and
thus failing?

I also worried about that. But it works fine.
Looks meson is smart enough. :-)

Sounds good to me.
Will take the suggestion in my v2.

Sorry, not to be skeptical, but at least with the meson version I was
using when doing something similar I'm sure this didn't work -
find_library just takes the parameter, adds "-l" in front of it and
uses it to compile.

In the meson configure log, do you see:

Dependency libmlx4 found: NO
Library libmlx4 found: YES

?

My understanding was the same as yours, Luca, and I'm pretty sure older
versions used to have that restriction. I think we should - out of an
abundance of caution - remove the "lib" prefix from all library/dependency
requests.

Thanks for the note, Luca.

It worked regardless. Compilation's done successfully and the final testpmd
binary was good to run. Don't know how it worked but will change it anyway. Not
a hard task. Here's the diff.

Then, it will give us:

Library mnl found: YES
Dependency libmlx5 found: NO
Library mlx5 found: YES
Dependency libibverbs found: NO
Library ibverbs found: YES
