In order to compile you need Cython installed.
Change one line in build.cmd:
call "D:\Soft\anaconda3\Scripts\activate.bat" "D:\Soft\anaconda3" to call "YourAnaconda3Path\Scripts\activate.bat" "YourAnaconda3Path"
Save your cython code in "yournewmodule.pyx" then run "build yournewmodule.pyx". This would compile your cython module and install it as a package in current anaconda env. To use it in other python files:
from yournewmodule import *
