The path to the driver executable must be set by the webdriver.gecko.driver system property - How must I do it?

I am executing a test plan using firefox driver config and I have downloaded the firefox driver i.e. geckodriver.exe and store it in a D: drive. Now I have used the firefox driver config in my test plan and don't know where to set the path for geckodriver.exe. Below I have shared the image for more information. Please refer to the same.
