Furthermore, I observed that cmake versions < 3.11 will not recognize the xlC compiler.  It is necessary to use cmake version >= 3.11 and use the following flag -qxlcompatmacros to define the macros. Lastly, I observed improved performance using the following flags \"-O3 -qhot -qarch=pwr8 -qtune=pwr8\"  (on the power8's) with the new simd macros.
