I get an error when building against OCCT v7.7.0 with the 0.20.2 pre-release tarball as well with the 0.20.2 tag from GitHub. The error does not show for current master HEAD.

The build system checks dependencies for workbenches during the configuration step and will warn you if a dependency is unsatisfied. FEM needs the PART workbench enabled, according to https://github.com/FreeCAD/FreeCAD/blob/master/cMake/FreeCAD_Helpers/CheckInterModuleDependencies.cmake#L23, but no ...

Sorry i missed that, but my point is, there was another 13 references to /usr/lib/qt6/moc correctly detected even without setting Qt6Core_MOC_EXECUTABLE Only this two references to graphviz was missed. That's because this case is handled separately from the other files, see https://github.com/FreeC...

If "Qt5WebEngineWidgets" provides a separate development package or SDK, be sure it has been installed. I have this package installed, so it looks like the path is missing: Package qt5-qtwebengine-5.15.10-2.fc36.x86_64 is already installed. (Fedora 36) Is there a separate -dev package for...

IMO your package manager should warn you, if two packages can't be installed at the same time.

No, Qt6 only supports the QtWebEngine module.

On Gentoo Linux we have it as a required runtime dependency, independently of any options set for the package. IIRC I tested it once and was not able to build FreeCAD without pyside being installed.

VTK uses an IMO good process to handle both Qt5 and Qt6. In https://gitlab.kitware.com/vtk/vtk/-/blob/v9.2.2/CMake/vtkQt.cmake they define a VTK_QT_VERSION variable, which will subsequently be used throughout the cmake files in the form of Qt${VTK_QT_VERSION}_Found on all Qt variables which use a ve...

Would you eventually be able to provide the complete output of the cmake configuration process? Your supplied info contains no information on what went wrong and the provided CMake{Output,Error}.log files contain mostly noise but not much to be able to help you with this issue. From your second comm...

The issues you describe are not related to FreeCAD, but to the distributions in case. FreeCAD works well with Python 3.10 if you build the dependencies against this version as well.
You could ask the respective package maintainers to update their packages or add versions which support Python 3.10.
