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.

                         either -opensource or -commercial)

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

                         With this switch you create a source incompatible version of Qt,
                         which is unsupported.

                         at run time.

    -no-pkg-config ..... Disable use of pkg-config.

                                     style assets from the run-time device. Setting this will
                                     make the Android style behave incorrectly, but will enable
                                     compatibility with the LGPL2.1 license.
 *  -android-style-assets .......... Compile the code which automatically extracts style assets
                                     from the run-time device. This option will make the
                                     Android platform plugin incompatible with the LGPL2.1.
