Merge branch 'backport-3.15-fix-EXCLUDE_FROM_ALL-subdir-all'

Resolve conflicts with changes since the 3.15 series:

* Convert `cmSystemTools::IsOn` => `cmIsOn`.
* Move one "EXCLUDE_FROM_ALL" target property logic fix to
  its new location in `cmMakefile::AddNewUtilityTarget`.

 EXCLUDE_FROM_ALL
 ----------------
 
-Exclude the directory from the all target of its parent.
+Set this directory property to a true value on a subdirectory to exclude
+its targets from the "all" target of its ancestors.  If excluded, running
+e.g. ``make`` in the parent directory will not build targets the
+subdirectory by default.  This does not affect the "all" target of the
+subdirectory itself.  Running e.g. ``make`` inside the subdirectory will
+still build its targets.
 
-A property on a directory that indicates if its targets are excluded
-from the default build target.  If it is not, then with a Makefile for
-example typing make will cause the targets to be built.  The same
-concept applies to the default build of other generators.
-
-Targets inherit the :prop_tgt:`EXCLUDE_FROM_ALL` property from the directory
-that they are created in. When a directory is excluded, all of its targets will
-have :prop_tgt:`EXCLUDE_FROM_ALL` set to ``TRUE``. After creating such a target
-you can change its :prop_tgt:`EXCLUDE_FROM_ALL` property to ``FALSE``. This
-will cause the target to be included in the default build target.
+If the :prop_tgt:`EXCLUDE_FROM_ALL` target property is set on a target
+then its value determines whether the target is included in the "all"
+target of this directory and its ancestors.
