Sure, but what if the package is localed elsewhere (i.e. not in the tree, 
but in a different Windows drive for example) ?

I mean, if the path was absolute, it would be just fine because we could 
still use the command like this :

>>   UTILITY_SOURCE(VTK_WRAP_TCL_EXE vtkWrapTcl ${VTK_SOURCE_DIR}/Wrapping 
>> vtkWrapTcl.c)

it would be just up to the user to prepend the current path in that case, 
am I right ?

But since it's relative, this prevent the command to be used in a different 
(non-relative) context, don't you think so ?
