grep -r "qt_qml_find_python"

qtbase/cmake/QtProcessConfigureArgs.cmake:defstub(qt_qml_find_python)
qtdeclarative/src/qml/configure.cmake:qt_qml_find_python(__qt_qml_python_path 
__qt_qml_python_found)
qtdeclarative/cmake/QtDeclarativeSetup.cmake:function(qt_qml_find_python 
out_var_path out_var_found)

Indeed, it seems to be a mandatory requirement for qtdeclarative only 
according to cmake files.

It seems also necessary when configuring the "./configure" way.

Apparently it is in qtdeclarative.
File is generated by qlalr

qtdeclarative/src/qml/CMakeLists.txt:qt_process_qlalr(Qml "$
{CMAKE_CURRENT_SOURCE_DIR}/parser/qqmljs.g" "${_qt_qlalr_flags}")

qtdeclarative/src/qmldevtools/CMakeLists.txt:qt_process_qlalr(QmlDevTools "$
{CMAKE_CURRENT_SOURCE_DIR}/../qml/parser/qqmljs.g" "${_qt_qlalr_flags}")

It seems that since the file is passed with its full path to qlalr, it then 
writes the full path in qqmljsparser_p.h

Workaround would be 
- to add this parameter '--no-lines' to qlalr, then these references are not 
in qqmljsparser_p.h
- or to call qlalr with a relative path

Right now file contains such lines
#line 185 "/build/...../qt6/qtdeclarative/src/qml/parser/qqmljs.g"
