bpo-30368: Update build_ssl.py to restore Perl-less building by jkloth · Pull Request #1805 · python/cpython

vstinner

OpenSSL 1.0.2 releases changed how files are copied in the makefile,
thus causing Perl to be required even for Python's "prepared" OpenSSL.
Now build_ssl.py does the requisite copies before running nmake.
* Updates SSL-linking projects to use the new include{suffix} directory
* build_ssl.py now only copies those files not handled by prepare_ssl.py
* Update SSL-linking projects to use the new include{suffix} directory
