No, CMake does not build out of source by default. CMake uses the
current directory by default :-)

No that I know of, that's because I rolled my own.

On Emacs proper, there is project.el which has a TODO about
project-build:

;; * Build tool related functionality.  Start with a `project-build'
;;   command, which should provide completions on tasks to run, and
;;   maybe allow entering some additional arguments.

which is a bit vague.

Creating your own command to be used instead of `compile' (or advising
it) is quite easy, so easy that the value of any future built-in
functionality is questionable given the vast differences on build setups
that you will find out there.
