System Workbench for STM32

I can see Build Steps, if I import ST sample code by "Import > General > Existing Projects into Workspace" form STM32Cube_FW_L4_V1.8.0.

But if I import my project by using "Import > C/C++ > Existing Code as Makefile Project" then I can't see Build Steps....><
The Settings only have "Binary Parsers" and "Error Parsers", didn't have "Build Steps"
how come??
