Branding compilation error

so i just checked, whether the branding capabilities of OF are still working, after i opened https://www.graphics.rwth-aachen.de:9000/OpenFlipper-Free/OpenFlipper-Free/merge_requests/283 but unfortunately i encountered an error during the compilation. Don't know whether i missed something necessary for branding as i only specified OPENFLIPPER_PRODUCT_STRING and OPENFLIPPER_PRODUCT_NAME in the branding.cmake which was located in the folder /OpenFlipper-Free/Package-Wurst/branding/branding.cmake

other than that make file, i did nothing for branding. However the error message is not very informative, even if i missed something that is necessary for branding OF, a warning or error message would be very helpful

here is the error message the compiler gives me:
