--disable-tls1          disable TLS1 protocol
  --disable-tls1_1        disable TLS1.1 protocol
  --disable-tls1_2        disable TLS1.2 protocol
  --disable-tls1_3        disable TLS1.3 protocol
  --enable-deterministic  enable deterministic DH parameters
  --enable-ssl-fastpath   enable using the underlying file descriptor for
                          talking directly to the SSL library
  --disable-hardening     enable hardening attempts
  --enable-static-ssl     enable static linking to the SSL library


Optional Packages:
  --with-PACKAGE[=ARG]    use PACKAGE [ARG=yes]
  --without-PACKAGE       do not use PACKAGE (same as --with-PACKAGE=no)
  --with-tcl              directory containing tcl configuration
                          (tclConfig.sh)
  --with-tcl8             Compile for Tcl8 in Tcl9 environment
  --with-tclinclude       directory containing the public Tcl header files
  --with-openssl-dir=<dir>
                          path to root directory of OpenSSL or LibreSSL
                          installation
  --with-openssl-pkgconfig=<dir>
                          path to root directory of OpenSSL or LibreSSL
                          pkgconfigdir
  --with-builtin-dh-params-size=<bits>
                          specify the size in bits of the built-in,
                          precomputed, DH params

Some influential environment variables:
  CC          C compiler command
  CFLAGS      C compiler flags
  LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
              nonstandard directory <lib dir>
  LIBS        libraries to pass to the linker, e.g. -l<library>
