Description

Stabililize the search routines for MOAB and double-down

Motivation and Context

• double-down installs its .cmake-files explicitly to a subdirectory dd. This PR adds that subdir to the search path explicitly. In cases cmake does not find them otherwise
• The MOAB search directory variable should be quoted. In some cases it can cause FindMOAB to fail. If it is installed to non-standard directory.

Changes

Bug-fix

Behavior

Old behaviour: can cause installation to fail.
New behaviour: more stable installation, less dependent on local cmake parameters.

Thanks @ebknudsen - this seems reasonable to me. I suppose we should be testing with DD at some point in our process - perhaps at merge time, even if not during PR review. Thoughts @pshriwise ?

[pshriwise]

Yes, I agree. I thought we were at some point. Did that go away?
