      <parameter>CFLAGS="-O2" CXXFLAGS="-O2"</parameter>: By default,
      <application>Autoconf</application> sets CFLAGS and CXXFLAGS to
      "-g -O2". That results in binaries and libraries being built with
      debugging symbols which make them bigger. Override the default
      flags to omit -g switch so the final libraries are smaller.

      <option>--enable-texture-float</option>: This switch enables
      floating-point textures and render buffers. Please consult

      any legal issues if you use this feature.
