Perl error on building.

When building with msvc i get the following error:

So the python script tries to call a perl script, which errors out because of some file not found error. I checked that Perl is in Path and verified that in the source folder "codegen" a perl-script named preprocess.pl is found.

I have no clue what file is not found.

I set visual studios verbosity up to get the exact call which, in my personal case, was:

C:\Python312\python.exe D:/Dev/Sources/qtwebkit-2022-09-07-src/Source/JavaScriptCore/inspector/scripts/generate-inspector-protocol-bindings.py --outputDir D:/Dev/Builds/qtwebkitcmake/JavaScriptCore/DerivedSources/inspector --framework JavaScriptCore D:/Dev/Builds/qtwebkitcmake/JavaScriptCore/DerivedSources/CombinedDomains.json

Executing this directly in the windows terminal succeded and generated some files in JavaScriptCore\DerivedSources\inspector

After that i restarted the build and it continued happily.

I'm leaving this open since i still dont know how to achieve this without manual interference.
