add_custom_command: convert DEPENDS path arguments to absolute paths

This is only done if they are "obviously" paths in that they contain a
directory separator.

+add_custom_command-depends-path
+-------------------------------
+
+* The :command:`add_custom_command` command learned to detect paths in
+  ``DEPENDS`` arguments and convert them to paths relative to the current
+  binary directory. This only applies to paths which contain a ``/`` or ``\\``
+  in them because names like ``filename.txt`` could also be target names and
+  cannot be coverted into absolute paths blindly.
