This script creates necessary configuration files to build/install.

Main options:
  --prefix=[path]       Base path for build/install.  Default: /usr/local
  --bindir=[path]       Directory for binaries.  Default: PREFIX/bin
  --datadir=[path]      Directory for data.  Default: PREFIX/share
  --qtdir=[path]        Directory where Qt is installed.
  --extraconf=[conf]    Extra configuration for nonstandard cases.
  --verbose             Show extra configure output.
  --qtselect=[N]        Select major Qt version (4 or 5).
