On CentOS, how do I build Python 3.9 from source while incorporating my openssl module?

I'm trying to build Python 3.9.1 with SSL support on CentOS 7.

[myuser@server Python-3.9.1]$ which openssl
/usr/local/bin/openssl
[myuser@server Python-3.9.1]$ openssl version
OpenSSL 1.1.1g  21 Apr 2020

Running this command

sudo ./configure CPPFLAGS="-I/usr/local/openssl/include" LDFLAGS="-L/usr/local/openssl/lib" --with-ssl

followed by "make" worked for Python 3.7, but when i run the above on 3.9 and then run make I get this output

...
Python build finished successfully!
The necessary bits to build these optional modules were not found:
_lzma                 _tkinter              _uuid              
To find the necessary bits, look in setup.py in detect_modules() for the module's name.


The following modules found by detect_modules() in setup.py, have been
built by the Makefile instead, as configured by the Setup files:
_abc                  atexit                pwd                
time                                                           


Following modules built successfully but were removed because they could not be imported:
_hashlib              _ssl                                     


Could not build the ssl module!
Python requires an OpenSSL 1.0.2 or 1.1 compatible libssl with X509_VERIFY_PARAM_set1_host().
LibreSSL 2.6.4 and earlier do not provide the necessary APIs, https://github.com/libressl-portable/portable/issues/381

So evidently Python 3.9 has NOT been built with SSL. What else do I need to do to build Python 3.9 with the openssl module I have installed?
