Hmm, that means CMAKE_INSTALL_PREFIX_INITIALIZED_TO_DEFAULT is *false*
when CMAKE_INSTALL_PREFIX is set explicitly, ...

I think I found what I did wrong after looking at more instances of
CMakeLists.txt files. When setting paths, I should use either something
like /usr/local/stow/trilinos (no quotes) or "/usr/local/stow/trilinos"
(double quotes) but *not* '/usr/local/stow/trilinos' (single quotes). I
had thought that as there are no special characters, they don't make any
difference. :-( Maybe the cmake experts out there can confirm.

Thanks again for all the timely help and greetings of the season,
ST
