Scan and review https://github.com/emweb/wt/blob/8ada2e04a1a5ced7e865769d19a9b69b183fc39a/doc/licenses.md?plain=1#L153 for correctness

[pombredanne]

See https://github.com/emweb/wt/blob/8ada2e04a1a5ced7e865769d19a9b69b183fc39a/doc/licenses.md?plain=1#L153 pasted below. The goal is to run license detection on this and review the results to ensure that the detections are correct. If not, add new rules as needed.

External dependencies

Wt's only essential external dependency, apart from system- and compiler-specific libraries, is Boost (https://www.boost.org).

The table below lists all of Wt's dependencies that are not system- or compiler-specific, depending on how Wt is configured. Note that this list is provided for reference. Since this is external software and not distributed as part of the Wt source code, their licenses may change.

OpenSAML

If Wt Auth is built with SAML support, Wt also depends on OpenSAML (and its dependencies).

:warning: Note: The license for OpenSAML is Apache License 2.0. This license is not compatible with the GNU General Public License v2 used by Wt. As a consequence, unless you use the commercial Wt license, you may not distribute derived works that use Wt with SAML support enabled.

These are additional dependencies if you enable SAML support:
