 ## Compiling for different CPUs
 The build system generally assumes an x86 cpu with AVX instructions (most modern x86 CPUs). To build on another kind of CPU (e.g. older than 2012) you can use the `FLUID_ARCH` cache variable to pass specific flags to your compiler. For example use `-DFLUID_ARCH=-mcpu=native` to optimize for your particular CPU.
