Providing path to zlib and Python when configuring LLVM?

I was able to specify the path to Python with “-DPYTHON_HOME=path/to/Python37-32”, but it says that the Python installation is corrupt and I don’t know how to fix that. It says there are three .exe files that it can’t find, but they still aren’t there even after I repaired my Python installation. For zlib I tried “-DZLIB_HOME=path/to/zlib” but it didn’t recognize that flag. So how should I do it?
