sip-build: There are no bindings that can be built

[Belz Ulrich]

Hello,

Following the documentation, I am trying to build PyQt6 from source (to 
enable qml debug):

PS C:\PyQt6-6.3.0> sip-build --no-make --qml-debug --confirm-license
Querying qmake about your Qt installation...
This is the GPL version of PyQt 6.3.0 (licensed under the GNU General 
Public License) for Python 3.10.4 on win32.
Found the license file 'pyqt-gpl.sip'.
Checking to see if the QtCore bindings can be built...
Checking to see if the QtNetwork bindings can be built...
Checking to see if the QtGui bindings can be built...
Checking to see if the QtQml bindings can be built...
Checking to see if the QtWidgets bindings can be built...
Checking to see if the QtDBus bindings can be built...
The QtDesigner bindings are disabled with a static Qt installation...
Checking to see if the QtHelp bindings can be built...
...
Checking to see if the QAxContainer bindings can be built...
sip-build: There are no bindings that can be built
PS C:\PyQt6-6.3.0> make
make: *** No targets specified and no makefile found.  Stop.
PS C:\PyQt6-6.3.0>

What's wrong?

Best regards,
