      <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. It is recommended that
      you override the default flags to omit -g switch so the final
      libraries are smaller.
