What QtCreator version do you use?
Can you open a command prompt and try to execute g++ (with full path and correct separators)? -

I am trying out Qt for the first time. When I tried to build the coffee machine example, CMake gave this error, and I haven't been able to solve it.

I'm not sure but can't you install CMake via Qt installer?

Using the QT CMake installation gives me this error:

@Christian-Ehrlicher I still get the same error

I still get the same error
Remove the build dir and run cmake again, if it still complains about it you still have a cygwin PATH somewhere - remove it.
