Building QT6.4 with static OpenSSL on Windows

Build static OpenSSL, read QT docs:

Configure QT as follows:

cd C:\dev\build\qt
  
"C:\Program Files\Microsoft Visual Studio\2022\Professional\VC\Auxiliary\Build\vcvarsall.bat" amd64
      
set "CMAKE_ROOT=C:\dev\PFiles\cmake-3.24.2-windows-x86_64\bin"
set "NINJA_ROOT=C:\dev\PFiles\ninja-win"
set "PERL_ROOT=C:\dev\PFiles\Strawberry\perl\bin"
      
set PATH=%CMAKE_ROOT%;%PATH%
set PATH=%NINJA_ROOT%;%PATH%
set PATH=%PERL_ROOT%;%PATH%
set PATH=C:\dev\PFiles\Python35;%PATH%
      
rem Check if the tools are in PATH
where perl.exe
where python.exe
where cmake.exe
where ninja.exe
      
set MY_INSTALL_PATH=C:/dev/libs/Qt6.4/windows
set MY_QT_SRC_DIR=C:\dev\repos\qt-everywhere-src-6.4.0
set MY_OPENSSL_DIR=C:/dev/libs/OpenSSL
set CL=/MP

The output should be the following:

WARNING: Basic cpp/winrt support missing. Some features might not be available.
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.
You will also need to set the FEATURE_clang CMake variable to ON to re-evaluate this check.
WARNING: Clang-based lupdate parser will not be available. LLVM and Clang C++ libraries have not been found.
You will need to set the FEATURE_clangcpp CMake variable to ON to re-evaluate this check.

Qt is now configured for building. Just run 'cmake --build . --parallel'

Once everything is built, you must run 'ninja install'
Qt will be installed into 'C:/dev/libs/Qt6.4/windows'

To configure and build other Qt modules, you can use the following convenience script:
        C:/dev/libs/Qt6.4/windows/bin/qt-configure-module.bat

If reconfiguration fails for some reason, try removing 'CMakeCache.txt' from the build directory

  1. dmitriano says:

    OPENSSL_ROOT_DIR and OPENSSL_USE_STATIC_LIBS variables are probably from here: https://github.com/Kitware/CMake/blob/master/Modules/FindOpenSSL.cmake#L124

  2. dmitriano says:

    installed Git from here: https://gitforwindows.org/

  3. dmitriano says:

    There also should be OPENSSL_MSVC_STATIC_RT=ON, see C:\dev\PFiles\cmake-3.24.2-windows-x86_64\share\cmake-3.24\Modules\FindOpenSSL.cmake
