Subject: fabrics: compile when libudev not installed
X-Git-Tag: v0.8~6
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=4a0549d99f16317f81731cc63515c3de4b5bea33;p=users%2Fsagi%2Fnvme-cli.git

fabrics: compile when libudev not installed

libudev is optional to use this repository. Packages can require it if
desired, but others downloading the repo should still be able to use
most of the functionality this tool provides without it.
