CCS/IWR6843: Setting up build environment

Tool/software: Code Composer Studio

I modified the source code and want to generate a bin file but my bin file after modified can't use with GUI.

My PC's OS is Windows 10.

My device is ES2. 

Code Composer Studio 8.3.1

mmwave_sdk_03_03_00_03

mmwave_industrial_toolbox_4_2_1

As I know, after modification, we need to setup the build environment. I checked setenv.bat, its path is correct.

@REM Select your device. Options (case sensitive) are: awr14xx, iwr14xx, awr16xx, iwr16xx, awr18xx, iwr18xx, iwr68xx
set MMWAVE_SDK_DEVICE=iwr68xx

@REM If download via CCS is needed, set below define to yes else no
@REM yes: Out file created can be loaded using CCS.
@REM Binary file created can be used to flash
@REM no: Out file created cannot be loaded using CCS.
@REM Binary file created can be used to flash 
@REM (additional features: write-protect of TCMA, etc)
set DOWNLOAD_FROM_CCS=yes

@REM If using a secure device this variable needs to be updated with the path to mmwave_secdev_<ver> folder
set MMWAVE_SECDEV_INSTALL_PATH=

@REM If using a secure device, this variable needs to be updated with the path to hsimage.cfg file that
@REM has customer specific certificate/key information. A sample hsimage.cfg file is in the secdev package
set MMWAVE_SECDEV_HSIMAGE_CFG=%MMWAVE_SECDEV_INSTALL_PATH%/hs_image_creator/hsimage.cfg

@REM Call script to check env variables and set paths

@REM Check error code

EXIT /B 0

Then I checked the method to build demo in windows

REM Fill <device type> with appropriate device that supports demo in a particular release
cd %MMWAVE_SDK_INSTALL_PATH%/ti/demo/<device type>/mmw

REM Clean and build
gmake clean
gmake all

REM Incremental build
gmake all

REM For example to build the mmw demo for iwr68xx
cd %MMWAVE_SDK_INSTALL_PATH%/ti/demo/xwr68xx/mmw
gmake clean
gmake all
REM This will create xwr68xx_mmw_demo_mss.xer4f & xwr68xx_mmw_demo.bin binaries
REM under %MMWAVE_SDK_INSTALL_PATH%/ti/demo/xwr68xx/mmw folder

I can't run these commands on Windows cmd. It said: "gmake is not recognized as an internal or external command". Even though I checked my Gmake version is 4.1 in the path C:\ti\ccsv8\utils\bin

How to generate bin file that can work with GUI normally in this case?
