llvm dev - May 2019 - 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?

Hi again, all.

I'm asking this here because I couldn't find it in the LLVM
documentation (if I overlooked something, please let me know and point me to
where it is): how do I specify the path to zlib and the path to Python when
configuring CMake for building LLVM?
