manual: add cmake project() directive for standalone operation

The cmake rules in the manual/ subdirectory are designed to work both in
the context of the application build, as well as for exclusive creation
of the manual.

Add a project() directive in the manual/ cmake rules. Its absence was
not fatal but resulted in warnings. This amends commit 074da67ee25a.
