// The right thing to do is to load the library at the major version we know how
// to work with: the SHLIB_VERSION_NUMBER version (macro defined in opensslv.h)
//
// However, OpenSSL is a well-known case of binary-compatibility breakage. To
// avoid such problems, many system integrators and Linux distributions change
// the soname of the binary, letting the full version number be the soname. So
// we'll find libssl.so.0.9.7, libssl.so.0.9.8, etc. in the system. For that
// reason, we will search a few common paths (see findAllLibSsl() above) in hopes
// we find one that works.
//
// If that fails, for OpenSSL 1.0 we also try some fallbacks -- look up
// libssl.so with a hardcoded soname. The reason is QTBUG-68156: the binary
// builds of Qt happen (at the time of this writing) on RHEL machines,
// which change SHLIB_VERSION_NUMBER to a non-portable string. When running
// those binaries on the target systems, this code won't pick up
// libssl.so.MODIFIED_SHLIB_VERSION_NUMBER because it doesn't exist there.
// Given that the only 1.0 supported release (at the time of this writing)
// is 1.0.2, with soname "1.0.0", give that a try too. Note that we mandate
// OpenSSL >= 1.0.0 with a configure-time check, and OpenSSL has kept binary
// compatibility between 1.0.0 and 1.0.2.
//
// It is important, however, to try the canonical name and the unversioned name
// without going through the loop. By not specifying a path, we let the system
// dlopen(3) function determine it for us. This will include any DT_RUNPATH or
// DT_RPATH tags on our library header as well as other system-specific search
// paths. See the man page for dlopen(3) on your system for more information.
