Usage:  $relconf [options]

Installation options:

 These are optional, but you may specify install directories.

    -prefix <dir> ...... The deployment directory, as seen on the target device.
                         (default /usr/local/Qt-${QT_VERSION}, \$PWD if -developer-build is active)

    -extprefix <dir> ... The installation directory, as seen on the host machine.
                         (default SYSROOT/PREFIX)

    -hostprefix [dir] .. The installation directory for build tools running on the
                         host machine. If [dir] is not given, the current build
                         directory will be used. (default EXTPREFIX)

 You may use these to change the layout of the install. Note that all directories
 except -sysconfdir should be located under -prefix/-hostprefix:

    -bindir <dir> ......... User executables will be installed to <dir>
                            (default PREFIX/bin)
    -headerdir <dir> ...... Headers will be installed to <dir>
                            (default PREFIX/include)

                            (default PREFIX)
    -plugindir <dir> ...... Plugins will be installed to <dir>
                            (default ARCHDATADIR/plugins)
    -libexecdir <dir> ..... Program executables will be installed to <dir>
                            (default ARCHDATADIR/libexec, ARCHDATADIR/bin for MinGW)
    -importdir <dir> ...... Imports for QML1 will be installed to <dir>
                            (default ARCHDATADIR/imports)
    -qmldir <dir> ......... Imports for QML2 will be installed to <dir>
                            (default ARCHDATADIR/qml)
    -datadir <dir> ........ Arch-independent data used by Qt will be installed to <dir>

                            (default DATADIR/doc)
    -translationdir <dir> . Translations of Qt programs will be installed to <dir>
                            (default DATADIR/translations)

Configure options:

 The defaults (*) are usually acceptable. A plus (+) denotes a default value
 that needs to be evaluated. If the evaluation succeeds, the feature is
 included. Here is a short explanation of each option:

 *  -release ........... Compile and link Qt with debugging turned off.
    -debug ............. Compile and link Qt with debugging turned on.
    -debug-and-release . Compile and link two versions of Qt, with and without
                         debugging turned on (Mac only).

    -force-debug-info .. Create symbol files for release builds.

    -developer-build ... Compile and link Qt with Qt developer options (including auto-tests exporting)

 *  -no-optimized-tools ... Do not build optimized host tools even in debug build.
    -optimized-tools ...... Build optimized host tools even in debug build.

    -opensource ........ Compile and link the Open-Source Edition of Qt.
    -commercial ........ Compile and link the Commercial Edition of Qt.

    -confirm-license ... Automatically acknowledge the license (use with
                         either -opensource or -commercial)

    -c++std <edition> .. Compile Qt with C++ standard edition (c++11, c++14, c++1z)
                         Default: highest supported

 *  -shared ............ Create and use shared Qt libraries.
    -static ............ Create and use static Qt libraries.

    -no-accessibility .. Do not compile Accessibility support.
                         Disabling accessibility is not recommended, as it will break QStyle
                         and may break other internal parts of Qt.
                         With this switch you create a source incompatible version of Qt,

        NOTICE: configure was unable to determine the architecture
        for the $XQMAKESPEC target.

        Qt will not use a specialized implementation for any atomic
        operations. Instead a generic implemention based on either GCC
        intrinsics or C++11 std::atomic<T> will be used (when
        available). The generic implementations are generally as fast
        as and always as safe as a specialized implementation.

        If no generic implementation is available, Qt will use a
        fallback UNIX implementation which uses a single
        pthread_mutex_t to protect all atomic operations. This
        implementation is the slow (but safe) fallback implementation
        for architectures Qt does not yet support.
