Daniele E. Domenichelli f598f1aa83 ExternalProject: Add ExternalProject_Add_StepDependencies function ...

The ExternalProject_Add_StepDependencies function add some dependencies
for some external project step.

The syntax is:
 ExternalProject_Add_Step_Dependencies(<name> <step> [target1 [target2 [...]]])

This function takes care to set both target and file level dependencies,
and will ensure that parallel builds will not break.

It should be used instead of add_dependencies() when adding a dependency
for some of the step targets generated by ExternalProject. See also:
