Usage: configure [options] [-- cmake-options]
This is a convenience script for configuring Qt with CMake.
Options after the double dash are directly passed to CMake.
Top-level installation directories:
-prefix <dir> ...... The deployment directory, as seen on the target device.
[/usr/local/Qt-$QT_VERSION; qtbase build directory if
-developer-build]
-no-prefix ......... The deployment directory is set to the qtbase build
directory. Can be used instead of -developer-build
to not have to install, as well as avoid
-developer-build's default of -warnings-are-errors.
-extprefix <dir> ... The installation directory, as seen on the host machine.
[SYSROOT/PREFIX]
Fine tuning of installation directory layout. Note that all directories
except -sysconfdir should be located under -prefix:
-bindir <dir> ......... Executables [PREFIX/bin]
-headerdir <dir> ...... Header files [PREFIX/include]
-libdir <dir> ......... Libraries [PREFIX/lib]
-archdatadir <dir> .... Arch-dependent data [PREFIX]
-plugindir <dir> ...... Plugins [ARCHDATADIR/plugins]
-libexecdir <dir> ..... Helper programs [ARCHDATADIR/bin on Windows,
ARCHDATADIR/libexec otherwise]
-qmldir <dir> ......... QML imports [ARCHDATADIR/qml]
-datadir <dir> ........ Arch-independent data [PREFIX]
-docdir <dir> ......... Documentation [DATADIR/doc]
-translationdir <dir> . Translations [DATADIR/translations]
-sysconfdir <dir> ..... Settings used by Qt programs [PREFIX/etc/xdg]
-examplesdir <dir> .... Examples [PREFIX/examples]
-testsdir <dir> ....... Tests [PREFIX/tests]
-hostdatadir <dir> .... Data used by qmake [PREFIX]
Conventions for the remaining options: When an option's description is
followed by a list of values in brackets, the interpretation is as follows:
'yes' represents the bare option; all other values are possible prefixes to
the option, e.g., -no-gui. Alternatively, the value can be assigned, e.g.,
--gui=yes. Values are listed in the order they are tried if not specified;
'auto' is a shorthand for 'yes/no'. Solitary 'yes' and 'no' represent binary
options without auto-detection.
Configure meta:
-help, -h ............ Display this help screen
-redo ................ Re-configure with previously used options. In addition,
redo removes CMakeCache.txt file and CMakeFiles/ directory
and recreates them from scratch.
Additional options may be passed, but will not be
saved for later use by -redo.
-feature-<feature> ... Enable <feature>
-no-feature-<feature> Disable <feature> [none]
-list-features ....... List available features. Note that some features
have dedicated command line options as well.
Build options:
-cmake-generator <name> ... Explicitly specify the build system generator for
CMake instead of auto-detecting one.
-cmake-use-default-generator ... Turn off auto-detection of the CMake build
system generator.
-cmake-file-api ...... Let CMake store build metadata for loading the build
into an IDE. [no; yes if -developer-build]

Note: this affects binary compatibility.
-R <string> .......... Add an explicit runtime library path to the Qt
libraries. Supports paths relative to LIBDIR.

used to remove all code deprecated in Qt 6.5.0 or
earlier releases.

build. The list should be separated with commas.
e.g. -skip qtimageformats,qtsvg
-make <part> ......... Add <part> to the list of parts to be built.
Specifying this option clears the default list first.

-gtk ................. Enable GTK platform theme support [auto]
-no-opengl ........... Disable OpenGL support
-opengl <api> ........ Enable OpenGL support. Supported APIs:
Remove ANGLE This marks the end of EGL and OpenGL ES support on Windows. The concepts of -opengl dynamic, -opengl desktop, QT_OPENGL=software, etc. remain unchanged, with the exception of the disapperance of everything ANGLE related. CMake builds now work identically to qmake on Windows: they default to 'dynamic' OpenGL on Windows, unless -DINPUT_opengl=desktop is specified. On Windows, Qt 6 is expected to default to the "dynamic" OpenGL model by default, just like Qt 5.15. This can be changed by switching to "desktop" OpenGL, which will link to opengl32 (publicly, so other libs and applications will do so as well) and disallows using another OpenGL DLL. The "dynamic" mode is essential still because the fallback to a software rasterizer, such as the opengl32sw.dll we ship with the Qt packages, has to to work exactly like in Qt 5, the removal of ANGLE does not change this concept in any way (except of course that the middle option of using ANGLE is now gone) When it comes to the windows plugin's OpenGL blacklist feature, it works like before and accepts the ANGLE/D3D related keywords. They will then be ignored. Similarly, requesting QT_OPENGL=angle is ignored (but will show a warning). The D3D11 and DXGI configure time tests are removed: Qt 5.14 already depends on D3D 11.1 and DXGI 1.3 headers being available unconditionally on Win32 (in QRhi's D3D11 backend). No need to test for these. [ChangeLog][Windows] ANGLE is no longer included with Qt. Dynamic OpenGL builds work like before but ANGLE is no longer an option. OpenGL proper or an alternative opengl32 implementation are the two remaining options now. Attempting to set QT_OPENGL=angle or Qt::AA_UseOpenGLES will have no effect on Windows.

3rdparty: remove xcb libs and bump minimal required version to 1.11 With libxcb 1.11 as minimal required version we can: (a) (Maybe) Enable threaded GL for MESA, see QTBUG-67277. (b) Avoid performance issues described in QTBUG-46017. Bundled xcb libs don't contain the more modern SHM fd passing APIs. The official binaries use "-qt-xcb", therefore we were shipping with the performance fix #ifdef-ed out. (c) Make xcb-xkb a mandatory dependency avoiding issues described in QTBUG-30911. Issues that appear when Qt was configure with "-no-xkb -xcb-xlib", but X server has the XKB extension. (d) Drop all, but xcb-xinput sources from src/3rdparty/xcb/, for which we need "xcb-xinput >= 1.12". This way we can reduce maintenance work. The xcb libraries were origianlly bundled because of lack of availability on supported distributions. This is not the case anymore: CI for Qt 5.13 has: Ubuntu 18.04 - libxcb 1.13 RHEL 7.4 - libxcb 1.13 openSUSE 15.0 - libxcb 1.13 CI for Qt 5.12 has: Ubuntu 16.04 - libxcb 1.11 RHEL 7.4 - libxcb 1.13 openSUSE 42.3 - libxcb 1.11 RHEL 6.x - not relevant because it was dropped from supported platforms. Why 1.11 (released on Aug, 2014), but not 1.13 (released on March 2018)? Based on what we have in CI for 5.13 and 5.14 we could update to 1.13, but it means that Qt would require a very recent version of 3rd party dependency.
