No support for AVX-128-FMA when building with cmake? #230

Hi,

using the configure script one can enable AVX-128-FMA (-mfma4 compiler flag) using the flag --enable-avx-128-fma. I don't see any such option to enable it when compiling with cmake. Am I missing something or is this missing in the cmake configuration?
