I want to compile POV-Ray with maximum support of hardware features,
including AVX2, for example. Could you tell me please, how to do that ?

And how can I know what features already supported by present binary ?
All I can see running the binary is:
---------------------------------------------------------------------
Dynamic optimizations:
   CPU detected: Intel,FMA3,FMA4
   Noise generator: generic (portable)
---------------------------------------------------------------------

I tried to configure it the following way:
---------------------------------------------------------------------
user@ruby3:~/projects/povray$ ./configure --enable-avx2 --without-x 
--prefix=/home/user/povray  COMPILED_BY="Yesbird <yes### [at] gmailcom>" 
| grep -i avx

configure: WARNING: unrecognized options: --enable-avx2
checking whether C++ compiler accepts -mavx... yes
checking whether C++ compiler accepts -mavx2... yes
---------------------------------------------------------------------
but as you can see without success.

My CPU support following flags:
---------------------------------------------------------------------
