[CMake] FORTRAN USE statement dependencies

[Joseph Winston]

I'm using the CVS head version of cmake and I've run into the  
following problem with the FORTRAN dependency generator and the USE  
statement.  cmake now creates modname.mod.stamp files and enters them  
into the dependency calculation.  However, the path to the  
modname.mod.stamp is incorrect because it assumes that none of the  
FORTRAN code is in a subdirectory.  The fix to the problem is to add  
the path in the dependency.  Here's a patch that does this.  One  
shortcoming is the patch uses the full path rather than the relative  
paths that are used elsewhere in the depend.make files.
