        [additional platform specific options (see below)]          
Installation options:
 These are optional, but you may specify install directories.
    -prefix <dir> ...... This will install everything relative to <dir>
                         (default /usr/local/Trolltech/QtopiaCore-4.3.3)
    -hostprefix [dir] .. Tools and libraries needed when developing
                         applications are installed in [dir]. If [dir] is
                         not given, the current build directory will be used.
  * -prefix-install .... Force a sandboxed "local" installation of
                         Qt. This will install into
                         /usr/local/Trolltech/QtopiaCore-4.3.3, if this option is
                         disabled then some platforms will attempt a
                         "system" install by placing default values to
                         be placed in a system location other than
                         PREFIX.
 You may use these to separate different parts of the install:
    -bindir <dir> ......... Executables will be installed to <dir>
                            (default PREFIX/bin)
    -libdir <dir> ......... Libraries will be installed to <dir>
                            (default PREFIX/lib)
    -docdir <dir> ......... Documentation will be installed to <dir>
                            (default PREFIX/doc)
    -headerdir <dir> ...... Headers will be installed to <dir>
                            (default PREFIX/include)
    -plugindir <dir> ...... Plugins will be installed to <dir>
                            (default PREFIX/plugins)
    -datadir <dir> ........ Data used by Qt programs will be installed to <dir>
                            (default PREFIX)
    -translationdir <dir>.. Translations of Qt programs will be installed to <dir>
                            (default PREFIX/translations)
    -sysconfdir <dir> ..... Settings used by Qt programs will be looked for in <dir>
                            (default PREFIX/etc/settings)
    -examplesdir <dir> .... Examples will be installed to <dir>
                            (default PREFIX/examples)
    -demosdir <dir> ....... Demos will be installed to <dir>
                            (default PREFIX/demos)
 You may use these options to turn on strict plugin loading.
    -buildkey <key> .... Build the Qt library and plugins using the specified
                         <key>.  When the library loads plugins, it will only
                         load those that have a matching key.
