Including the Sacado Speed Tests

Purpose
If Sacado is installed on your system, you can specify a value for its install sacado_prefix on the cmake command line. The value of sacado_prefix must be such that, for one of the directories dir in cmake_install_includedirs ,       sacado_prefix/dir/Sacado.hpp  is a valid way to reference to the include file Sacado.hpp;
If you include sacado_prefix on the cmake command line, you will be able to run the Sacado speed correctness tests by executing the following commands starting in the distribution directory :       cd build/speed/sacado      make check_speed_sacado  After executing make check_speed_sacado, you can run a specific Sacado speed test by executing the command ./speed_sacado; see speed_main for the meaning of the command line options to this program.
If you are using Unix, you can download and install a copy of Sacado using get_sacado.sh . The corresponding sacado_prefix would be build/prefix.
