CmdStan install 'make' issue on Windows 10

I installed CmdStan from the “stan-dev” Github repo by following the directions at 1 CmdStan Installation | CmdStan User’s Guide. However, when running the Stan compiler bernoulli example, I have the following error. (I am on GNU Make version 4.2.1)

Thanks in advance for any help.
