Looking at the regexps here [FindBoost.cmake](https://gitlab.kitware.com/cmake/cmake/-/blob/master/Modules/FindBoost.cmake#L393)

there is accounting only for 2 digit versions of python

Also the extra back slash is confusing

[alexander.grund@tu-dresden.de](mailto:alexander.grund@tu-dresden.de) perhaps you have an idea how to extend to 2 digit minor versions

Also in the syntax like Boost::python39 is that another part of cmake?
