In my defence I must say that the above mentioned
meson-/ninja-constructs are used only once in all of BLFS-12.3 (sysv),
namely in chapter "glib-2.82.5":

.../BLFS/BLFS-12.3> grep -n 'meson setup [[:alpha:]]\+.*\\$'
BLFS-BOOK-12.3-sysv-nochunks.html
44731:meson setup gobject-introspection-1.82.0 gi-build \

.../BLFS/BLFS-12.3> grep -n 'ninja -C [[:alpha:]]\+.*'
BLFS-BOOK-12.3-sysv-nochunks.html
44733:ninja -C gi-build</kbd></pre>
44736:                <span class="command"><strong>ninja -C gi-build
44746:              "command">ninja -C gi-build install</kbd></pre>

So I think it's fair to say that these constructs are unusual, at least
for LFS/BLFS.  And thus I think that users with less
meson-/ninja-expertise than the editor who wrote that stuff should be
given a helping hand by a short explanation or reference to the
meson-/ninja-documentation.

OTOH: as I seem to be the only one who complained, all other users
either are meson-/ninja-experts, had the bright idea to check the
meson-/ninja-documentation - or just didn't care (enough).  So perhaps
the chapter can just as well be left as it is. ;)
