Why can't you use the "PRE_BUILD" options of add_custom_command

It is not possible because this script should be run before any target?
I was looking at using targets do make sure the script only once and did
so before any target. I supposed I could use it PRE_BUILD option of one
of my libraries that everything else depends on...
Technically, that command could run when CMake is invoked (ie before any
build invocation). In that case, if the generator is Visual Studio, I
would simple run the script twice, once with parameters compatible for
debug, once for release... Is there a way to do that?

Did have a look at "generator expressions" they are meant to be used
in your precise case,
i.e. they are evaluated at "build time" and not at CMake time.
well I can only use those for parameters for the command. I would want
to specify a configuration dependant OUTPUT value.
I suppose I could do 2 commands, add a target for each of them.
But then how to do I do configuration dependent DEPEND rules when
calling ADD_DEPENDENCIES for my other libs?
