Hi Amul,
The -march flag doesn't automatically get set by CMake since it tends to be
highly system specific; you'll need to explicitly add it to your
CMAKE_{C,CXX,Fortran}_FLAGS variables if you want it used. The
CMAKE_SYSTEM_PROCESSOR variable is usually used only for packaging to
determine output file names and in cross compiling.
