qtgraphicaleffects - Unknown CMake command "add_qml_module"

I clone recursively qt5 superproject (branch 6.2) and I build qt5 superproject.

qtgraphicaleffects  is always defined as submodule (cf .gitmodules)

qtgraphicaleffects submodule should be remove from qt5 superproject submodule.

Moreover, I build in command line using cmake tool. if QT_BUILD_SUBMODULES is not defined in cmake options (CMAKE_OPTIONS="${CMAKE_OPTIONS} -DQT_BUILD_SUBMODULES=qtbase;....." in the command line, the default QT_BUILD_SUBMODULES variable contains qtgraphicaleffects in qt5 superproject.

qtgraphicalseffects should be remove from the default QT_BUILD_SUBMODULES variable.

If I define my own QT_BUILD_SUBMODULES list (without qtgraphicaleffects), all is build correctly.
