Subject: examples/l2fwd-keepalive: skip meson build if no librt
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=b334236abd8dfeea625525de548b35b40cb68c3b;p=dpdk.git

examples/l2fwd-keepalive: skip meson build if no librt

When librt is not present on a system, processing the meson.build file
for this example application causes an error. Make the library
non-mandatory and just mark the example as unbuildable if it is
not present.

Fixes: 89f0711f9ddf ("examples: build some samples with meson")
