Building QT6.4 on Ubuntu 22.04

I installed required packages:

sudo apt install build-essential
sudo apt install libx11-dev
sudo apt install ninja-build
sudo apt install openssl libssl-dev
sudo apt install libmd4c-dev libmd4c-html0-dev
sudo apt install pkg-config
sudo apt install mesa-utils libglu1-mesa-dev freeglut3-dev mesa-common-dev
sudo apt install libglew-dev libglfw3-dev libglm-dev
sudo apt install libao-dev libmpg123-dev

configured QT as follows:

cd ~
mkdir repos
cd repos
tar xf /mnt/d/dev.distrib/qt-everywhere-src-6.4.0.tar.xz
cd ~
mkdir -p build/qt
cd build/qt
export MY_INSTALL_PATH=/home/def/libs/QT6.4
export QT_SRC_PATH=/home/def/repos/qt-everywhere-src-6.4.0

${QT_SRC_PATH}/configure -prefix $MY_INSTALL_PATH -DQT_NO_EXCEPTIONS=1 -debug-and-release -force-debug-info -opensource -confirm-license \
  -c++std c++20 -static -static-runtime -openssl-linked \
  -skip qt3d -skip qt5compat -skip qtactiveqt -skip qtcharts -skip qtcoap -skip qtconnectivity \
  -skip qtdatavis3d -skip qtdoc -skip qtlottie -skip qtmqtt -skip qtnetworkauth -skip qtopcua \
  -skip qtserialport -skip qtpositioning -skip qtquicktimeline -skip qtquick3d -skip qtremoteobjects \
  -skip qtscxml -skip qtsensors -skip qtserialbus -skip qtvirtualkeyboard -skip qtwayland \
  -skip qtwebchannel -skip qtwebengine -skip qtwebview -skip qtquick3dphysics -skip qtspeech -skip qtlocation \
  -skip qthttpserver

and got the following output:

+ mkdir -p qtbase
+ cd qtbase
+ exec /home/def/repos/qt-everywhere-src-6.4.0/qtbase/configure -top-level -prefix /home/def/libs/QT6.4 -DQT_NO_EXCEPTIONS=1 -debug-and-release -force-debug-info -opensource -confirm-license -c++std c++20 -static -static-runtime -openssl-linked -skip qt3d -skip qt5compat -skip qtactiveqt -skip qtcharts -skip qtcoap -skip qtconnectivity -skip qtdatavis3d -skip qtdoc -skip qtlottie -skip qtmqtt -skip qtnetworkauth -skip qtopcua -skip qtserialport -skip qtpositioning -skip qtquicktimeline -skip qtquick3d -skip qtremoteobjects -skip qtscxml -skip qtsensors -skip qtserialbus -skip qtvirtualkeyboard -skip qtwayland -skip qtwebchannel -skip qtwebengine -skip qtwebview -skip qtquick3dphysics -skip qtspeech -skip qtlocation -skip qthttpserver

Note: Using static linking will disable the use of dynamically loaded plugins. Make sure to import all needed static plugins, or compile needed modules into the library.
Note: When linking against OpenSSL, you can override the default library names through OPENSSL_LIBS. For example: OPENSSL_LIBS='-L/opt/ssl/lib -lssl -lcrypto' ./configure -openssl-linked

WARNING: Feature static_runtime is insignificant in this configuration, ignoring related command line option(s).
WARNING: No backend for low level audio found.
WARNING: QDoc will not be compiled, probably because libclang could not be located. This means that you cannot build the Qt documentation.
Either set CMAKE_PREFIX_PATH or LLVM_INSTALL_DIR to the location of your llvm installation.
On Linux systems, you may be able to install libclang by installing the libclang-dev or libclang-devel package, depending on your distribution.
On macOS, you can use Homebrew's llvm package.

To configure and build other Qt modules, you can use the following convenience script:
