Hi,
it seems build.bat is not finding CMake from command line.
Make sure you can run cmake from command line. If you cannot, you will need to find the way to have the command CMake available. I would guess you need modify the environmental variable PATH to something like PATH=...\ProgramFiles\CMake\bin and run the console again. You can investigate how to do this. Once you have cmake available, you should be able to build fuzzylite using build.bat.
Cheers.
