  script_tag(name:"insight", value:"OpenSSL has internal defaults for a directory tree where it can find a
  configuration file as well as certificates used for verification in TLS. This directory is most commonly referred
  to as OPENSSLDIR, and is configurable with the --prefix / --openssldir configuration options.

  For OpenSSL versions 1.1.0 and 1.1.1, the mingw configuration targets assume that resulting programs and
  libraries are installed in a Unix-like environment and the default prefix for program installation as well as for
  OPENSSLDIR should be '/usr/local'.

  However, mingw programs are Windows programs, and as such, find themselves looking at sub-directories of
  'C:/usr/local', which may be world writable, which enables untrusted users to modify OpenSSL's default
  configuration, insert CA certificates, modify (or even replace) existing engine modules, etc.

  For OpenSSL 1.0.2, '/usr/local/ssl' is used as default for OPENSSLDIR on all Unix and Windows targets, including
  Visual C builds.  However, some build instructions for the diverse Windows targets on 1.0.2 encourage you to
  specify your own --prefix.");
