QT static link, error message

[humdidumdi]

Using this tutorial I wanted to bind QT static: https://boffinblogger.blogspot.com/2018/12/static-compile-of-qt-5120-using-visual.html

After running nmake I get an error message:

lib /NOLOGO  /OUT:C:\Qt\static\lib\Qt5Bootstrap.lib @C:\Users\Sinus\AppData\Local\Temp\nm33BA.tmp
        cd tools\moc\ && ( if not exist Makefile C:\Qt\Static\qtbase\bin\qmake.exe -o Makefile C:\Qt\Static\qtbase\src\tools\moc\moc.pro ) && "C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Tools\MSVC\14.27.29110\bin\HostX86\x86\nmake.exe" -f Makefile
Project ERROR: Unknown module(s) in QT: bootstrap-private

Stop.
NMAKE : fatal error U1077: "cd": Rückgabe-Code "0x2"

NMAKE : fatal error U1077: "cd": Rückgabe-Code "0x2"

What am I doing wrong?

PS: I use VS2019 with the msvc and the 32Bit version.
