Subject: VWR-10579: Fix NDOF.cmake to do the right thing on standalone.

The old one just assumed that libndof is installed,
even on standalone.

This patch looks for it on standalone, unless configured
with -DNDOF:BOOL=OFF, and when not found prints an error
message (including telling about -DNDOF:BOOL=OFF).
