[CMake] Help with custom targets

[Ulrik Mikaelsson]

Alright!

So how do I create a custom target?

Looking at the documentation, ADD_CUSTOM_TARGET seems to always
recompile, since it is not associated with any output, and
ADD_CUSTOM_COMMAND(target ...) seems to only be able to add commands
to existing targets?
