Starting with bpo-31399 Python will require some OpenSSL 1.0.2 features. The features are not available in LibreSSL yet. There is no easy way to detect the feature from setup.py. The inc_dir variable in setup.py does not reflect CPPFLAG. I tried "self.compiler.preprocess()" but run into more issues. For example prints to stderr in error cases.
https://www.gnu.org/software/autoconf-archive/ax_check_openssl.html makes it easy to check for working OpenSSL. It uses either pkg-config or falls back to manual detection in common locations.
Based on the M4 macro it is easy to check for features like working X509_VERIFY_PARAM_set1_host() function.
