+# We could add -DGMMLIB_ARCH=generic to make it use -march=generic

+# the baseline of CPUs supported by gmmlib all fit under 'corei7'.
+# They also add many '-msse*' flags, but they are all supported

+# intel-media-driver, which is wholly optional and installed only on
+# systems with supported CPUs, it doesn't make sense to change the
+# compilers flag in use.
