Getting qt source

git clone git://code.qt.io/qt/qt5.git qt6
cd qt6
git checkout origin/6.5.0 -b 6.5.0
git submodule update --init --recursive

Building

We are going to build Qt in debug first and release later

md build\debug
cd build\debug
@rem save current PATH
set ORIGINAL_PATH=%PATH%
@rem NOTE: libclang must be at the end otherwise cmake will use clang insted of msvc
set PATH=%PATH%;C:\Dev\libclang\debug\bin
@rem to skip modules: -skip qtwebengine
..\..\configure.bat -no-pch -skip qtwebengine -debug -prefix C:\dev\Qt\6.5
cmake --build . --parallel
cmake --install .

cd ..\..

md build\release
cd build\release
set PATH=%ORIGINAL_PATH%
set PATH=%PATH%;C:\Dev\libclang\release\bin
..\..\configure.bat -no-pch -skip qtwebengine -release -prefix C:\dev\Qt\6.5
cmake --build . --parallel
cmake --install .

Documentation

Documentation will be build with the release version of Qt

@rem inside build\release
cmake --build . --target docs
cmake --build . --target install_docs

cd build
cmake -DCMAKE_BUILD_TYPE=Release -G Ninja ..
cmake --build . --config Release
