Imported Keil uVision Project Fails to compile


I imported my Keil uvision project to DS  but it fails to compile


make all
process_begin: CreateProcess(NULL, echo "Building file: C:/XXX/XXX/Development Studio Workspace/BLE_Dongle/BLE_Dongle/PNG_3RD_Middlewares/ST/STM32_WPAN/utilities/otp.c", ...) failed.
make (e=2): The system cannot find the file specified.

make: *** [utilities/ utilities/otp.o] Error 2
"make all" terminated with exit code 2. Build might be incomplete.

I see the file in repo
