System Workbench for STM32

Hi,
I would like to start my first G4 project with "No firmware" option, however all of its depended driver are missing such as

\ldscripts
\ldscripts\libs.ld
\ldscriptsmem.ld
\ldscriptssections.ld

\system\
\system\include
\system\include\arm
\system\include\cmsis
\system\include\cortexm
\system\include\DEVICE
\system\include\diag

\system\src\cmsis
\system\src\cortexm
\system\src\DEVICE
\system\src\diag
\system\src\newlib

can anyone teach me how to generate project with above missing or needed drivers ?

many thanks in advance,

Tiger
