trying to builld rtos dji psdk sample ubuntu

Question

I'm trying to build rtos c sample from dji psdk here but I messed around with CmakeLists.txt. Here is what I've tried :

goto armgcc folder (contain CMakeLists.txt) run cmake -G "Unix Makefiles" toget an makefile (I don't know if it's good)

CMake Warning:
  No source or binary directory provided.  Both will be assumed to be the
  same as the current working directory, but note that this warning will
  become a fatal error in future CMake releases.

After that I've tried make to build :

I want to build the sample for the dev board stm32f4. It's look like if the compiler used is not arm-none-eabi-gcc, is someone has already build psdk from command line with armgcc ?
