Hi Ross, Bill and Nuno,

First of all, thanks very much for your help.

Ross, yes. CMake did read the file as other options were set and things
compiled without any error.

Bill, Numo, setting PyTrilinos_INSTALL_PREFIX via the -D option showed
"PyTrilinos installation path:
/usr/local/stow/trilinos/lib/python2.7/site-packages/PyTrilinos" which
exactly what I wanted.

It seems somehow when used inside an option file, it is not passed down
when pytrilinos is being configured. I'm quite new to cmake so I don't
know whether my use of the option file is 100% correct or not. And I
don't quite understand this few lines (in CMakeLists.txt in the
pytrilinos package).

IF(CMAKE_INSTALL_PREFIX_INITIALIZED_TO_DEFAULT)
  SET(PyTrilinos_DEFAULT_INSTALL_PREFIX ${PYTHON_PREFIX})
ELSE(CMAKE_INSTALL_PREFIX_INITIALIZED_TO_DEFAULT)
  SET(PyTrilinos_DEFAULT_INSTALL_PREFIX ${CMAKE_INSTALL_PREFIX})
ENDIF(CMAKE_INSTALL_PREFIX_INITIALIZED_TO_DEFAULT)

I got the idea of setting CMAKE_INSTALL_PREFIX from it. Maybe someone
can throw more light on this.

Regards,
ST
