I was going to say something incredulous, but... yeah, when you're
talking about a *Qt* project, by the time you get done mentioning
AUTOMOC and .ui files, you're talking at least a half dozen lines of
CMake logic. So I can see the use :-).

I'm not sure if this belongs in CMake *itself*, but I think having a
script (Python? Bash? Other?) to do it would be a great idea. It could
take options to control behavior:

  - project name
  - executable name (if different from project)
  - C++ standard version (optional with a sensible default)
  - ...others?
