Subject: meson: wrap the whole tools section inside an if block
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=c57b5e3eb38d3f78f3caa63256bd33401f6617f5;p=thirdparty%2Fkmod.git

meson: wrap the whole tools section inside an if block

At the moment, we leave random bits out of the `if get_option('tools')`
block (internal/static libkmod, kmod.pc and internal symlinks).

The latter of which, is annotated as build_by_default:true, which means
it always pulls the executable - kmod - and ultimatelly, we build all
tools related artefacts even with -Dtools=false.

Just wrap the whole section and simplify the executable() a bit. Namely:
use install: true and drop build_by_default.
