Enable hardware optimizations
-----------------------------
Depending on target platfrom architecture different instruction sets can be used. By default
Depending on target platform architecture different instruction sets can be used. By default
compiler generates code for armv5l without VFPv3 and NEON extensions. Add ``-DUSE_VFPV3=ON``
to cmake command line to enable code generation for VFPv3 and ``-DUSE_NEON=ON`` for using
NEON SIMD extensions.
