whoop - somewhat down the make skript suddenly well known gcc switches appear and hours later:
Processed 1 file, writing output (x86-unicode):
Output: “C:\data\ki\kicad-winbuilder\msys64\home\jv\out\pack-x86_64\kicad-r14321.89e9857f3-x86_64.exe”
Kicad Installation runs without errors but after invoking, kicad.exe stops becouse of missing libzstd.dll for what I have to dig again
