Fixed CMAKE_PREFIX_PATH issue.

This adds quotes around CMAKE_PREFIX_PATH in the patch. The lack
of them was causing problems when CMAKE_PREFIX_PATH had multiple
items.

-    ParaView propagates CMAKE_PREFIX_PATH to Catalyst Adaptors.
-
-    Fixes #18224
-    ParaView uses add_custom_command to build all the catalyst adaptors.
-    This means that any package find calls that occur when including
-    ParaView's Config Module need to be part of the search path for
-    the adaptor.
-
-    The easiest way is to make sure that CMAKE_PREFIX_PATH is propagated
-    through add_custom_command as it is the most common way of specifying
-    where to search.
-
-    Note: That as more projects move over to import targets this approach
-    will continue to fail especially if they specify the search directories
-    using `<Package>_ROOT`. Long term the catalyst adaptors will need to
-    become an external project or stop using add_custom_command.
+The calls to cmake in BuildAdaptors were passing CMAKE_PREFIX_PATH to cmake calls without quoting
+it. That worked fine for when CMAKE_PREFIX_PATH wasn't set or was a single item, but when it was a
+list it broke the builds of the adaptors.
