Subject: [PATCH] CMake: make build of documentation optional (#842)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

So we don't need to support corner cases as for example one fixed in
commit f6202db308e3 ("doc/MANUAL.adoc: Don't use non-ASCII quotes
(#761)") when the documentation is actually not needed at all as ccache
is used as a build tool only.
