[CMake] ADD_CUSTOM_COMMAND and Dependencies

[Micha Renner]

There is following sequence:

ADD_EXECUTEABLE(generator gen.c)

ADD_CUSTOM_COMMAND(OUTPUT tlib.h
	COMMAND generator > tlib.h)

ADD_LIBRARY(tlib tlib.c tlib.h)

The question: Is it sure that ADD_EXECUTEABLE is invoked before the
library is build or is here an ADD_DEPENDENCIES(tlib generator)
necessary?

Greetings
