I have selected option for "STM32 Firmware Library package" -> "copy only the necessery library files".
I'm using just LL libraries and GPDSC project.
All files ware generated without error but no startup file was present in the project, only blank directories "arm", "gcc" and "iar" ware created in directory "Drivers/CMSIS/Device/ST/STM32F0xx/Source/Templates/"
On the other hand, it copies "system_stm32f0xx.c" in "Templates" directory, which is not needed, because similar file is generated with the same name and functionality to the "Src" directory.
PC OS: Linux
CubeMX version: 4.23.0
Firmware package: STM32Cube FW_F0 V1.9.0
