<hr>

<p>Thank you for your reply.</p>

<p>How I can pass these flags? which command line I have to use, an example plz?</p>

<p>Also running:</p>

<pre><code> sudo cat /proc/cpuinfo | grep flags
</code></pre>

<p>Gives:</p>

<pre><code>    flags       : fpu vme de pse tsc msr pae mce cx8 apic mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe nx rdtscp lm constant_tsc arch_perfmon pebs bts xtopology nonstop_tsc aperfmperf pni pclmulqdq dtes64 monitor ds_cpl vmx est tm2 ssse3 cx16 xtpr pdcm sse4_1 sse4_2 x2apic popcnt xsave avx lahf_lm ida arat epb xsaveopt pln pts dts tpr_shadow vnmi flexpriority ept vpid

<p>I already have this option in my cmakefile</p>

<pre><code>if (SSE3_FOUND)
  set (CMAKE_C_FLAGS_ALL "${CMAKE_C_FLAGS_ALL} -msse3")
endif()
if (SSSE3_FOUND)
  set (CMAKE_C_FLAGS_ALL "${CMAKE_C_FLAGS_ALL} -mssse3")
endif()
if (SSE4_1_FOUND)
  set (CMAKE_C_FLAGS_ALL "${CMAKE_C_FLAGS_ALL} -msse4.1")
endif()
if (SSE4_2_FOUND)
  set (CMAKE_C_FLAGS_ALL "${CMAKE_C_FLAGS_ALL} -msse4.2")
endif()
