Building QtWebEngine 6.7.2 : "Could not find a configuration file for package "Qt6" that is compatible with requested version "6.5"."

kamui

Hi,

I'm trying to build QtWebEngine 6.7.2 with proprietary codecs on Windows, but when calling cmake it fails, saying Qt 6.5 is requested.

What I did :

git clone git://code.qt.io/qt/qtwebengine.git
cd qtwebengine
git checkout 6.7.2
git submodule update --init --progress


mkdir build
cd build
C:\Qt\6.7.2\msvc2019_64\bin\qt-configure-module.bat .. -webengine-proprietary-codecs

The output :

-- Windows 10 SDK version: 10.0.22621.0
'C:\Qt\6.7.2\msvc2019_64\bin\qt-cmake-private.bat' '-DQT_INTERNAL_CALLED_FROM_CONFIGURE:BOOL=TRUE' '-DINPUT_webengine_proprietary_codecs=yes' 'C:/qt6/qtwebengine'

CMake Error at CMakeLists.txt:14 (find_package):
  Could not find a configuration file for package "Qt6" that is compatible
  with requested version "6.5".

  The following configuration files were considered but not accepted:

    C:/Qt/6.7.2/msvc2019_64/lib/cmake/Qt6/Qt6Config.cmake, version: 6.7.2 (64bit)


-- Configuring incomplete, errors occurred!

CMake Error at C:/Qt/6.7.2/msvc2019_64/lib/cmake/Qt6/QtProcessConfigureArgs.cmake:1077 (message):
  CMake exited with code 1.

I also tried this, producing the same result :

cmake -D CMAKE_MESSAGE_LOG_LEVEL=STATUS -D QT_FEATURE_webengine_proprietary_codecs=ON -D QT_BUILD_EXAMPLES_BY_DEFAULT=OFF -G Ninja ..

Finally, I tried the following instruction (same without ninja), making the configuration process work but the generation fail :

cmake -D CMAKE_MESSAGE_LOG_LEVEL=STATUS -D QT_FEATURE_webengine_proprietary_codecs=ON -D QT_BUILD_EXAMPLES_BY_DEFAULT=OFF ..

[...]
-- Configuring done (35.8s)
CMake Error in CMakeLists.txt:
  The EXCLUDE_FROM_ALL property of target "qwebengine_convert_dict" varies by
  configuration.  This is not supported by the "Visual Studio 17 2022"
  generator.


-- Generating done (2.8s)
CMake Generate step failed.  Build files cannot be regenerated correctly.

The versions of the binaries implied :

Cmake 3.30
Ninja 1.12.1
Qt 6.7.2
Windows 10
msvc 19.41.34120

Any idea of what is missing here ?

Thank you for your help.

You can’t build webengine alone.
